[{"scopus_import":"1","intvolume":" 17","month":"06","abstract":[{"lang":"eng","text":"AgSbSe2 is a promising thermoelectric (TE) p-type material for applications in the middle-temperature range. AgSbSe2 is characterized by relatively low thermal conductivities and high Seebeck coefficients, but its main limitation is moderate electrical conductivity. Herein, we detail an efficient and scalable hot-injection synthesis route to produce AgSbSe2 nanocrystals (NCs). To increase the carrier concentration and improve the electrical conductivity, these NCs are doped with Sn2+ on Sb3+ sites. Upon processing, the Sn2+ chemical state is conserved using a reducing NaBH4 solution to displace the organic ligand and anneal the material under a forming gas flow. The TE properties of the dense materials obtained from the consolidation of the NCs using a hot pressing are then characterized. The presence of Sn2+ ions replacing Sb3+ significantly increases the charge carrier concentration and, consequently, the electrical conductivity. Opportunely, the measured Seebeck coefficient varied within a small range upon Sn doping. The excellent performance obtained when Sn2+ ions are prevented from oxidation is rationalized by modeling the system. Calculated band structures disclosed that Sn doping induces convergence of the AgSbSe2 valence bands, accounting for an enhanced electronic effective mass. The dramatically enhanced carrier transport leads to a maximized power factor for AgSb0.98Sn0.02Se2 of 0.63 mW m–1 K–2 at 640 K. Thermally, phonon scattering is significantly enhanced in the NC-based materials, yielding an ultralow thermal conductivity of 0.3 W mK–1 at 666 K. Overall, a record-high figure of merit (zT) is obtained at 666 K for AgSb0.98Sn0.02Se2 at zT = 1.37, well above the values obtained for undoped AgSbSe2, at zT = 0.58 and state-of-art Pb- and Te-free materials, which makes AgSb0.98Sn0.02Se2 an excellent p-type candidate for medium-temperature TE applications."}],"oa_version":"None","pmid":1,"volume":17,"issue":"12","publication_status":"published","publication_identifier":{"eissn":["1936-086X"],"issn":["1936-0851"]},"language":[{"iso":"eng"}],"article_type":"original","type":"journal_article","status":"public","_id":"13235","department":[{"_id":"MaIb"}],"date_updated":"2023-08-02T06:29:55Z","quality_controlled":"1","publisher":"American Chemical Society","acknowledgement":"Y.L. acknowledges funding from the National Natural Science Foundation of China (NSFC) (Grants No. 22209034), the Innovation and Entrepreneurship Project of Overseas Returnees in Anhui Province (Grant No. 2022LCX002).

In contrast, Cu2–xTe, another member of the copper chalcogenide family, typically exhibits low Seebeck coefficients that limit its potential to achieve a superior thermoelectric figure of merit, zT, particularly in the low-temperature range where this material could be effective. To address this, we investigated the TE performance of Cu1.5–xTe–Cu2Se nanocomposites by consolidating surface-engineered Cu1.5Te nanocrystals. This surface engineering strategy allows for precise adjustment of Cu/Te ratios and results in a reversible phase transition at around 600 K in Cu1.5–xTe–Cu2Se nanocomposites, as systematically confirmed by in situ high-temperature X-ray diffraction combined with differential scanning calorimetry analysis. The phase transition leads to a conversion from metallic-like to semiconducting-like TE properties. Additionally, a layer of Cu2Se generated around Cu1.5–xTe nanoparticles effectively inhibits Cu1.5–xTe grain growth, minimizing thermal conductivity and decreasing hole concentration. These properties indicate that copper telluride based compounds have a promising thermoelectric potential, translated into a high dimensionless zT of 1.3 at 560 K.","lang":"eng"}],"pmid":1,"oa_version":"None"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2024-01-08T09:17:04Z","citation":{"mla":"Wan, Shanhong, et al. “Band Engineering through Pb-Doping of Nanocrystal Building Blocks to Enhance Thermoelectric Performance in Cu3SbSe4.” Small Methods, Wiley, 2023, doi:10.1002/smtd.202301377.","ama":"Wan S, Xiao S, Li M, et al.

After ligand displacement and annealing treatments, the dried powders are consolidated into dense pellets, and their TE properties are investigated. Pb doping effectively increases the charge carrier concentration, resulting in a significant increase in electrical conductivity, while the Seebeck coefficients remain consistently high. The calculated band structure shows that Pb doping induces band convergence, thereby increasing the effective mass. Furthermore, the large ionic radius of Pb2+ results in the generation of additional point and plane defects and interphases, dramatically enhancing phonon scattering, which significantly decreases the lattice thermal conductivity at high temperatures.

One possibility is employing surfactant-free solution synthesis to produce nanopowders. We propose the strategy of functionalizing “naked” particles’ surface by inorganic molecules to control the nanostructure and, consequently, thermoelectric performance. In particular, we use bismuth thiolates to functionalize surfactant-free SnTe particles’ surfaces. Upon thermal processing, bismuth thiolates decomposition renders SnTe-Bi2S3 nanocomposites with synergistic functions: 1) carrier concentration optimization by Bi doping; 2) Seebeck coefficient enhancement and bipolar effect suppression by energy filtering; and 3) lattice thermal conductivity reduction by small grain domains, grain boundaries and nanostructuration. Overall, the SnTe-Bi2S3 nanocomposites exhibit peak z T up to 1.3 at 873 K and an average z T of ≈0.6 at 300–873 K, which is among the highest reported for solution-processed SnTe."}],"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"oa_version":"Published Version","scopus_import":"1","intvolume":" 61","month":"08","publication_status":"published","publication_identifier":{"issn":["1433-7851"],"eissn":["1521-3773"]},"language":[{"iso":"eng"}],"file":[{"relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"checksum":"ad601f2b9e26e46ab4785162be58b5ed","file_id":"12476","creator":"dernst","file_size":4072650,"date_updated":"2023-02-02T08:01:00Z","file_name":"2022_AngewandteChemieInternat_Chang.pdf","date_created":"2023-02-02T08:01:00Z"}],"ec_funded":1,"volume":61,"issue":"35","_id":"11705","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","status":"public","date_updated":"2023-08-03T12:23:52Z","ddc":["540"],"file_date_updated":"2023-02-02T08:01:00Z","department":[{"_id":"MaIb"},{"_id":"EM-Fac"}]},{"acknowledgement":"This work was supported by the European Regional Development Funds.

Subsequently, nanoparticles are annealed in a reducing atmosphere to remove surface oxide, and consolidated into dense polycrystalline materials by means of spark plasma sintering. By characterizing the transport properties of the sintered material, we observe the annealing step and the incorporation of Cu to play a key role in promoting the thermoelectric performance of PbS. The presence of Cu allows improving the electrical conductivity by increasing the charge carrier concentration and simultaneously maintaining a large charge carrier mobility, which overall translates into record power factors at ambient temperature, 2.3 mWm-1K−2. Simultaneously, the lattice thermal conductivity decreases with the introduction of Cu, leading to a record high ZT = 0.37 at room temperature and ZT = 1.22 at 773 K.

However, solution synthesis generally involves the presence of additional molecules or ions belonging to the precursors or added to enable solubility and/or regulate nucleation and growth. These molecules or ions can end up in the particles as surface adsorbates and interfere in the material properties. This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically adsorbed in SnSe particles synthesized in water and play a crucial role not only in directing the material nano/microstructure but also in determining the transport properties of the consolidated material. In dense pellets prepared by sintering SnSe particles, Na remains within the crystal lattice as dopant, in dislocations, precipitates, and forming grain boundary complexions. These results highlight the importance of considering all the possible unintentional impurities to establish proper structure-property relationships and control material properties in solution-processed thermoelectric materials."}],"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"oa_version":"Published Version","pmid":1,"scopus_import":"1","intvolume":" 33","month":"12","date_updated":"2023-08-14T07:25:27Z","ddc":["620"],"file_date_updated":"2022-02-03T13:16:14Z","department":[{"_id":"EM-Fac"},{"_id":"MaIb"}],"_id":"10123","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","keyword":["mechanical engineering","mechanics of materials","general materials science"],"status":"public","year":"2021","has_accepted_license":"1","isi":1,"publication":"Advanced Materials","day":"29","date_created":"2021-10-11T20:07:24Z","date_published":"2021-12-29T00:00:00Z","doi":"10.1002/adma.202106858","acknowledgement":"Y.L. and M.C. contributed equally to this work.

Bi2Se3 is an obvious possible Te-free alternative to Bi2Te3 for ambient temperature thermoelectric applications, but its performance is still low for practical applications, and additional efforts toward finding proper dopants are required. Here, we report a scalable method to produce Bi2Se3 nanosheets at low synthesis temperatures. We studied the influence of different dopants on the thermoelectric properties of this material. Among the elements tested, we demonstrated that Sn doping resulted in the best performance.

Towards solving these current challenges, in the present work, we detail a low temperature solution-based approach to produce Bi2Te3-Cu2-xTe nanocomposites with improved thermoelectric performance. Our approach consists in combining proper ratios of colloidal nanoparticles and to consolidate the resulting mixture into nanocomposites using a hot press. The transport properties of the nanocomposites are characterized and compared with those of pure Bi2Te3 nanomaterials obtained following the same procedure. In contrast with most previous works, the presence of Cu2-xTe nanodomains does not result in a significant reduction of the lattice thermal conductivity of the reference Bi2Te3 nanomaterial, which is already very low. However, the introduction of Cu2-xTe yields a nearly threefold increase of the power factor associated to a simultaneous increase of the Seebeck coefficient and electrical conductivity at temperatures above 400 K. Taking into account the band alignment of the two materials, we rationalize this increase by considering that Cu2-xTe nanostructures, with a relatively low electron affinity, are able to inject electrons into Bi2Te3, enhancing in this way its electrical conductivity. The simultaneous increase of the Seebeck coefficient is related to the energy filtering of charge carriers at energy barriers within Bi2Te3 domains associated with the accumulation of electrons in regions nearby a Cu2-xTe/Bi2Te3 heterojunction. Overall, with the incorporation of a proper amount of Cu2-xTe nanoparticles, we demonstrate a 250% improvement of the thermoelectric figure of merit of Bi2Te3."}],"oa_version":"Submitted Version","main_file_link":[{"url":"https://ddd.uab.cat/record/271949","open_access":"1"}],"scopus_import":"1","intvolume":" 418","month":"08","publication_status":"published","publication_identifier":{"issn":["1385-8947"]},"language":[{"iso":"eng"}],"ec_funded":1,"volume":418,"issue":"8"},{"title":"Doping-mediated stabilization of copper vacancies to promote thermoelectric properties of Cu2-xS","article_processing_charge":"No","external_id":{"isi":["000663442200004"]},"author":[{"first_name":"Yu","last_name":"Zhang","full_name":"Zhang, Yu"},{"first_name":"Congcong","full_name":"Xing, Congcong","last_name":"Xing"},{"last_name":"Liu","orcid":"0000-0001-7313-6740","full_name":"Liu, Yu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu"},{"full_name":"Spadaro, Maria Chiara","last_name":"Spadaro","first_name":"Maria Chiara"},{"full_name":"Wang, Xiang","last_name":"Wang","first_name":"Xiang"},{"full_name":"Li, Mengyao","last_name":"Li","first_name":"Mengyao"},{"last_name":"Xiao","full_name":"Xiao, Ke","first_name":"Ke"},{"first_name":"Ting","last_name":"Zhang","full_name":"Zhang, Ting"},{"full_name":"Guardia, Pablo","last_name":"Guardia","first_name":"Pablo"},{"full_name":"Lim, Khak Ho","last_name":"Lim","first_name":"Khak Ho"},{"full_name":"Moghaddam, Ahmad Ostovari","last_name":"Moghaddam","first_name":"Ahmad Ostovari"},{"full_name":"Llorca, Jordi","last_name":"Llorca","first_name":"Jordi"},{"first_name":"Jordi","full_name":"Arbiol, Jordi","last_name":"Arbiol"},{"first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","last_name":"Ibáñez"},{"first_name":"Andreu","last_name":"Cabot","full_name":"Cabot, Andreu"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Zhang Y, Xing C, Liu Y, et al.

Here, semiconductor–metal composites are produced by just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution and at room temperature with a metallic Cu powder. The obtained blend is annealed in a reducing atmosphere and afterward consolidated into dense polycrystalline pellets through spark plasma sintering (SPS). We observe that, during the annealing process, the presence of metallic copper activates a partial reduction of the PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic lead during the SPS process habilitates the liquid-phase sintering of the composite. Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites, and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate that the presence of metallic lead decisively contributes to a strong increase of the charge carrier concentration through spillover of charge carriers enabled by the low work function of lead. The increase in charge carrier concentration translates into much higher electrical conductivities and moderately lower Seebeck coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2 at ambient temperature, well above those of PbS and PbS + CuxS. Additionally, the presence of multiple phases in the final composite results in a notable decrease in the lattice thermal conductivity. Overall, the introduction of metallic copper in the initial blend results in a significant improvement of the thermoelectric performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT = 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides, an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.","lang":"eng"}]},{"main_file_link":[{"open_access":"1","url":"https://upcommons.upc.edu/bitstream/handle/2117/363528/Pb%20mengyao.pdf?sequence=1&isAllowed=y"}],"scopus_import":"1","intvolume":" 15","month":"03","abstract":[{"text":"Cu2–xS has become one of the most promising thermoelectric materials for application in the middle-high temperature range. Its advantages include the abundance, low cost, and safety of its elements and a high performance at relatively elevated temperatures. However, stability issues limit its operation current and temperature, thus calling for the optimization of the material performance in the middle temperature range. Here, we present a synthetic protocol for large scale production of covellite CuS nanoparticles at ambient temperature and atmosphere, and using water as a solvent. The crystal phase and stoichiometry of the particles are afterward tuned through an annealing process at a moderate temperature under inert or reducing atmosphere. While annealing under argon results in Cu1.8S nanopowder with a rhombohedral crystal phase, annealing in an atmosphere containing hydrogen leads to tetragonal Cu1.96S. High temperature X-ray diffraction analysis shows the material annealed in argon to transform to the cubic phase at ca. 400 K, while the material annealed in the presence of hydrogen undergoes two phase transitions, first to hexagonal and then to the cubic structure. The annealing atmosphere, temperature, and time allow adjustment of the density of copper vacancies and thus tuning of the charge carrier concentration and material transport properties. In this direction, the material annealed under Ar is characterized by higher electrical conductivities but lower Seebeck coefficients than the material annealed in the presence of hydrogen. By optimizing the charge carrier concentration through the annealing time, Cu2–xS with record figures of merit in the middle temperature range, up to 1.41 at 710 K, is obtained. We finally demonstrate that this strategy, based on a low-cost and scalable solution synthesis process, is also suitable for the production of high performance Cu2–xS layers using high throughput and cost-effective printing technologies.","lang":"eng"}],"pmid":1,"oa_version":"Submitted Version","issue":"3","volume":15,"publication_status":"published","publication_identifier":{"eissn":["1936-086X"],"issn":["1936-0851"]},"language":[{"iso":"eng"}],"article_type":"original","type":"journal_article","keyword":["General Engineering","General Physics and Astronomy","General Materials Science"],"status":"public","_id":"9235","department":[{"_id":"MaIb"}],"date_updated":"2023-10-03T09:59:55Z","oa":1,"quality_controlled":"1","publisher":"American Chemical Society ","acknowledgement":"This work was supported by the European Regional Development Funds.

Therefore, to exploit the full potential of nanocrystal building blocks to produce functional nanomaterials and thin films, a proper control of their surface chemistry is required. Here, we analyze how the ligand stripping procedure influences the charge and heat transport properties of sintered PbSe nanomaterials produced from the bottom-up assembly of colloidal PbSe nanocrystals. First, we show that the removal of the native organic ligands by thermal decomposition in an inert atmosphere leaves relatively large amounts of carbon at the crystal interfaces. This carbon blocks crystal growth during consolidation and at the same time hampers charge and heat transport through the final nanomaterial. Second, we demonstrate that, by stripping ligands from the nanocrystal surface before consolidation, nanomaterials with larger crystal domains, lower porosity, and higher charge carrier concentrations are obtained, thus resulting in nanomaterials with higher electrical and thermal conductivities. In addition, the ligand displacement leaves the nanocrystal surface unprotected, facilitating oxidation and chalcogen evaporation. The influence of the ligand displacement on the nanomaterial charge transport properties is rationalized here using a two-band model based on the standard Boltzmann transport equation with the relaxation time approximation. Finally, we present an application of the produced functional nanomaterials by modeling, fabricating, and testing a simple PbSe-based thermoelectric device with a ring geometry.","lang":"eng"}],"ec_funded":1,"volume":3,"issue":"3","language":[{"iso":"eng"}],"file":[{"date_updated":"2022-08-23T08:34:17Z","file_size":6423548,"creator":"dernst","date_created":"2022-08-23T08:34:17Z","file_name":"2020_ACSAppliedEnergyMat_Cadavid.pdf","content_type":"application/pdf","access_level":"open_access","relation":"main_file","file_id":"11942","checksum":"f23be731a766a480c77c962c1380315c","success":1}],"publication_status":"published","publication_identifier":{"eissn":["2574-0962"]},"project":[{"grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"title":"Influence of the ligand stripping on the transport properties of nanoparticle-based PbSe nanomaterials","external_id":{"isi":["000526598300012"]},"article_processing_charge":"No","author":[{"last_name":"Cadavid","full_name":"Cadavid, Doris","first_name":"Doris"},{"first_name":"Silvia","full_name":"Ortega, Silvia","last_name":"Ortega"},{"first_name":"Sergio","full_name":"Illera, Sergio","last_name":"Illera"},{"last_name":"Liu","full_name":"Liu, Yu","orcid":"0000-0001-7313-6740","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu"},{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","full_name":"Ibáñez, Maria","orcid":"0000-0001-5013-2843","last_name":"Ibáñez"},{"first_name":"Alexey","last_name":"Shavel","full_name":"Shavel, Alexey"},{"full_name":"Zhang, Yu","last_name":"Zhang","first_name":"Yu"},{"first_name":"Mengyao","full_name":"Li, Mengyao","last_name":"Li"},{"last_name":"López","full_name":"López, Antonio M.","first_name":"Antonio M."},{"last_name":"Noriega","full_name":"Noriega, Germán","first_name":"Germán"},{"last_name":"Durá","full_name":"Durá, Oscar Juan","first_name":"Oscar Juan"},{"first_name":"M.

Our strategy is based on the formulation of a molecular precursor that can be continuously decomposed to produce a SnSe powder or printed into predefined patterns. The precursor formulation and decomposition conditions are optimized to produce pure phase 2D SnSe nanoplates. The printed layer and the bulk material obtained after hot press displays a clear preferential orientation of the crystallographic domains, resulting in an ultralow thermal conductivity of 0.55 W m–1 K–1 in the direction normal to the substrate. Such textured nanomaterials present highly anisotropic properties with the best thermoelectric performance in plane, i.e., in the directions parallel to the substrate, which coincide with the crystallographic bc plane of SnSe. This is an unfortunate characteristic because thermoelectric devices are designed to create/harvest temperature gradients in the direction normal to the substrate. We further demonstrate that this limitation can be overcome with the introduction of small amounts of tellurium in the precursor. The presence of tellurium allows one to reduce the band gap and increase both the charge carrier concentration and the mobility, especially the cross plane, with a minimal decrease of the Seebeck coefficient.

We first detail a two-step solution-based process to produce Bi2Te3–Cu2xTe heteronanostructures, based on the growth of Cu2xTe nanocrystals on the surface of Bi2Te3 nanowires. We characterize the structural and chemical properties of the synthesized nanostructures and of the nanocomposites\r\nproduced by hot-pressing the particles at moderate temperatures. Besides, the transport properties of the nanocomposites are investigated as a function of the amount of Cu introduced. Overall, the presence of Cu decreases the material thermal conductivity through promotion of phonon scattering, modulates the charge carrier concentration through electron spillover, and increases the Seebeck coefficient through filtering of charge carriers at energy barriers.

Colloidal synthetic routes allow for an exquisite control over such “artificial atoms” in terms of size, shape, and crystal phase as well as core and surface compositions. We present here a bottom-up approach to produce Pb–Ag–K–S–Te nanocomposites, which is a highly promising system for thermoelectric energy conversion. First, we developed a high-yield and scalable colloidal synthesis route to uniform lead sulfide (PbS) nanorods, whose tips are made of silver sulfide (Ag2S). We then took advantage of the large surface-to-volume ratio to introduce a p-type dopant (K) by replacing native organic ligands with K2Te. Upon thermal consolidation, K2Te-surface modified PbS–Ag2S nanorods yield p-type doped nanocomposites with PbTe and PbS as major phases and Ag2S and Ag2Te as embedded nanoinclusions. Thermoelectric characterization of such consolidated nanosolids showed a high thermoelectric figure-of-merit of 1 at 620 K.","lang":"eng"}],"ec_funded":1,"volume":13,"issue":"6","language":[{"iso":"eng"}],"file":[{"creator":"dernst","file_size":8628690,"date_updated":"2020-07-14T12:47:33Z","file_name":"2019_ACSNano_Ibanez.pdf","date_created":"2019-07-16T14:17:09Z","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_id":"6644"}],"publication_status":"published","publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"project":[{"grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"title":"Tuning transport properties in thermoelectric nanocomposites through inorganic ligands and heterostructured building blocks","article_processing_charge":"Yes (in subscription journal)","external_id":{"pmid":["31185159"],"isi":["000473248300043"]},"author":[{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","last_name":"Ibáñez"},{"full_name":"Genç, Aziz","last_name":"Genç","first_name":"Aziz"},{"first_name":"Roger","last_name":"Hasler","full_name":"Hasler, Roger"},{"full_name":"Liu, Yu","orcid":"0000-0001-7313-6740","last_name":"Liu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu"},{"full_name":"Dobrozhan, Oleksandr","last_name":"Dobrozhan","first_name":"Oleksandr"},{"first_name":"Olga","full_name":"Nazarenko, Olga","last_name":"Nazarenko"},{"first_name":"María de la","full_name":"Mata, María de la","last_name":"Mata"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"},{"first_name":"Maksym V.","last_name":"Kovalenko","full_name":"Kovalenko, Maksym V."}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Ibáñez, Maria, et al. “Tuning Transport Properties in Thermoelectric Nanocomposites through Inorganic Ligands and Heterostructured Building Blocks.” ACS Nano, vol. 13, no. 6, American Chemical Society, 2019, pp. 6572–80, doi:10.1021/acsnano.9b00346.","short":"M.

However, its cost-effectiveness is seriously hampered by the relatively high production cost and low efficiency of current thermoelectric materials and devices. To overcome present challenges and enable a successful deployment of thermoelectric systems in their wide application range, materials with significantly improved performance need to be developed. Nanostructuration can help in several ways to reach the very particular group of properties required to achieve high thermoelectric performances. Nanodomains inserted within a crystalline matrix can provide large charge carrier concentrations without strongly influencing their mobility, thus allowing to reach very high electrical conductivities. Nanostructured materials contain numerous grain boundaries that efficiently scatter mid- and long-wavelength phonons thus reducing the thermal conductivity. Furthermore, nanocrystalline domains can enhance the Seebeck coefficient by modifying the density of states and/or providing type- and energy-dependent charge carrier scattering. All these advantages can only be reached when engineering a complex type of material, nanocomposites, with exquisite control over structural and chemical parameters at multiple length scales. Since current conventional nanomaterial production technologies lack such level of control, alternative strategies need to be developed and adjusted to the specifics of the field. A particularly suitable approach to produce nanocomposites with unique level of control over their structural and compositional parameters is their bottom-up engineering from solution-processed nanoparticles. In this work, we review the state-of-the-art of this technology applied to the thermoelectric field, including the synthesis of nanoparticles of suitable materials with precisely engineered composition and surface chemistry, their combination and consolidation into nanostructured materials, the strategies to electronically dope such materials and the attempts to fabricate thermoelectric devices using nanoparticle-based nanopowders and inks."}],"pmid":1,"oa_version":"None","month":"06","intvolume":" 46","date_updated":"2024-03-05T12:21:43Z","extern":"1","_id":"374","type":"journal_article","article_type":"original","status":"public","year":"2017","day":"21","publication":"Chemical Society Reviews","page":"3510 - 3528","date_published":"2017-06-21T00:00:00Z","doi":"10.1039/c6cs00567e","date_created":"2018-12-11T11:46:06Z","acknowledgement":"This work was supported by the European Regional Development Funds, the Spanish Ministerio de Econom?a y Competitividad through the projects BOOSTER (ENE2013-46624-C4-3-R) and SEHTOP (ENE2016-77798-C4-3-R).

Here we present a simple and versatile bottom-up strategy based on the assembly of colloidal nanocrystals to produce consolidated yet nanostructured thermoelectric materials. In the case study on the PbS-Ag system, Ag nanodomains not only contribute to block phonon propagation, but also provide electrons to the PbS host semiconductor and reduce the PbS intergrain energy barriers for charge transport.

In such applications, the use of solution-processed nanocrystals (NCs) to produce thin films or bulk nanomaterials has associated several potential advantages, such as high material yield and throughput, and composition control with unmatched spatial resolution and cost. Here we report on the production of Cu3SbSe4 (CASe) NCs with tuned amounts of Sn and Bi dopants. After proper ligand removal, as monitored by nuclear magnetic resonance and infrared spectroscopy, these NCs were used to produce dense CASe bulk nanomaterials for solid state TE energy conversion. By adjusting the amount of extrinsic dopants, dimensionless TE figures of merit (ZT) up to 1.26 at 673 K were reached. Such high ZT values are related to an optimized carrier concentration by Sn doping, a minimized lattice thermal conductivity due to efficient phonon scattering at point defects and grain boundaries, and to an increase of the Seebeck coefficient obtained by a modification of the electronic band structure with Bi doping. Nanomaterials were further employed to fabricate ring-shaped TE generators to be coupled to hot pipes, which provided 20 mV and 1 mW per TE element when exposed to a 160 °C temperature gradient. The simple design and good thermal contact associated with the ring geometry and the potential low cost of the material solution processing may allow the fabrication of TE generators with short payback times.","lang":"eng"}],"doi":"10.1039/C6TA08467B","date_published":"2016-12-19T00:00:00Z","volume":5,"issue":"6","date_created":"2018-12-11T11:46:05Z","page":"2592 - 2602","day":"19","language":[{"iso":"eng"}],"publication":"Journal of Materials Chemistry A","publication_status":"published","year":"2016","status":"public","type":"journal_article","_id":"370","title":"Solution based synthesis and processing of Sn and Bi doped Cu inf 3 inf SbSe inf 4 inf nanocrystals nanomaterials and ring shaped thermoelectric generators","publist_id":"7457","author":[{"first_name":"Yu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","last_name":"Liu","orcid":"0000-0001-7313-6740","full_name":"Liu, Yu"},{"last_name":"García","full_name":"García, Gregorio","first_name":"Gregorio"},{"last_name":"Ortega","full_name":"Ortega, Silvia","first_name":"Silvia"},{"full_name":"Cadavid, Doris","last_name":"Cadavid","first_name":"Doris"},{"first_name":"Pablo","last_name":"Palacios","full_name":"Palacios, Pablo"},{"first_name":"Jinyu","last_name":"Lu","full_name":"Lu, Jinyu"},{"first_name":"Maria","last_name":"Ibanez","full_name":"Ibanez, Maria"},{"first_name":"Lili","full_name":"Xi, Lili","last_name":"Xi"},{"first_name":"Jonathan","full_name":"De Roo, Jonathan","last_name":"De Roo"},{"last_name":"López","full_name":"López, Antonio","first_name":"Antonio"},{"last_name":"Márti Sánchez","full_name":"Márti Sánchez, Sara","first_name":"Sara"},{"first_name":"Ignasi","last_name":"Cabezas","full_name":"Cabezas, Ignasi"},{"first_name":"Maria","full_name":"De La Mata, Maria","last_name":"De La Mata"},{"first_name":"Zhishan","last_name":"Luo","full_name":"Luo, Zhishan"},{"last_name":"Dun","full_name":"Dun, Chaocha","first_name":"Chaocha"},{"first_name":"Oleksandr","full_name":"Dobrozhan, Oleksandr","last_name":"Dobrozhan"},{"last_name":"Carroll","full_name":"Carroll, David","first_name":"David"},{"full_name":"Zhang, Wenging","last_name":"Zhang","first_name":"Wenging"},{"first_name":"José","last_name":"Martins","full_name":"Martins, José"},{"last_name":"Kovalenko","full_name":"Kovalenko, Mksym","first_name":"Mksym"},{"last_name":"Arbiol","full_name":"Arbiol, Jordi","first_name":"Jordi"},{"first_name":"German","full_name":"Noriega, German","last_name":"Noriega"},{"first_name":"Jiming","last_name":"Song","full_name":"Song, Jiming"},{"full_name":"Wahnón, Perla","last_name":"Wahnón","first_name":"Perla"},{"last_name":"Cabot","full_name":"Cabot, Andreu","first_name":"Andreu"}],"extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Liu, Yu, Gregorio García, Silvia Ortega, Doris Cadavid, Pablo Palacios, Jinyu Lu, Maria Ibanez, et al. “Solution Based Synthesis and Processing of Sn and Bi Doped Cu Inf 3 Inf SbSe Inf 4 Inf Nanocrystals Nanomaterials and Ring Shaped Thermoelectric Generators.” Journal of Materials Chemistry A.

Here, we present our experimental results on the thermal and electrical transport properties of PbS-metal composites produced by a versatile particle blending procedure, and where the metal work function allows injecting electrons to the intrinsic PbS host. We compare the thermoelectric performance of composites with microcrystalline or nanocrystalline structures. The electrical conductivity of the microcrystalline host can be increased several orders of magnitude with the metal inclusion, while relatively high Seebeck coefficient can be simultaneously conserved. On the other hand, in nanostructured materials, the host crystallites are not able to sustain a band bending at its interface with the metal, becoming flooded with electrons. This translates into even higher electrical conductivities than the microcrystalline material, but at the expense of lower Seebeck coefficient values.","lang":"eng"}],"oa_version":"None","publisher":"American Institute of Physics","intvolume":" 4","month":"08"},{"date_created":"2018-12-11T11:46:09Z","doi":"10.1021/acsami.6b02786","date_published":"2016-06-20T00:00:00Z","volume":8,"page":"17435 - 17444","publication":"ACS Applied Materials and Interfaces","language":[{"iso":"eng"}],"day":"20","year":"2016","publication_status":"published","intvolume":" 8","month":"06","publisher":"American Chemical Society","acknowledgement":"his work was supported by the European Regional Development Funds and the Spanish MINECO projects BOOSTER (ENE2013-46624-C4-3-R), TNT-FUELS (MAT2014-59961), e-TNT (MAT2014-59961-C2-2-R) and PEC-CO2 (ENE2012- 3651).
