--- res: bibo_abstract: - Cesium lead halides have intrinsically unstable crystal lattices and easily transform within perovskite and nonperovskite structures. In this work, we explore the conversion of the perovskite CsPbBr3 into Cs4PbBr6 in the presence of PbS at 450 °C to produce doped nanocrystal-based composites with embedded Cs4PbBr6 nanoprecipitates. We show that PbBr2 is extracted from CsPbBr3 and diffuses into the PbS lattice with a consequent increase in the concentration of free charge carriers. This new doping strategy enables the adjustment of the density of charge carriers between 1019 and 1020 cm–3, and it may serve as a general strategy for doping other nanocrystal-based semiconductors.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Mariano foaf_name: Calcabrini, Mariano foaf_surname: Calcabrini foaf_workInfoHomepage: http://www.librecat.org/personId=45D7531A-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Aziz foaf_name: Genc, Aziz foaf_surname: Genc - foaf_Person: foaf_givenName: Yu foaf_name: Liu, Yu foaf_surname: Liu foaf_workInfoHomepage: http://www.librecat.org/personId=2A70014E-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-7313-6740 - foaf_Person: foaf_givenName: Tobias foaf_name: Kleinhanns, Tobias foaf_surname: Kleinhanns foaf_workInfoHomepage: http://www.librecat.org/personId=8BD9DE16-AB3C-11E9-9C8C-2A03E6697425 - foaf_Person: foaf_givenName: Seungho foaf_name: Lee, Seungho foaf_surname: Lee foaf_workInfoHomepage: http://www.librecat.org/personId=BB243B88-D767-11E9-B658-BC13E6697425 orcid: 0000-0002-6962-8598 - foaf_Person: foaf_givenName: Dmitry N. foaf_name: Dirin, Dmitry N. foaf_surname: Dirin - foaf_Person: foaf_givenName: Quinten A. foaf_name: Akkerman, Quinten A. foaf_surname: Akkerman - foaf_Person: foaf_givenName: Maksym V. foaf_name: Kovalenko, Maksym V. foaf_surname: Kovalenko - foaf_Person: foaf_givenName: Jordi foaf_name: Arbiol, Jordi foaf_surname: Arbiol - foaf_Person: foaf_givenName: Maria foaf_name: Ibáñez, Maria foaf_surname: Ibáñez foaf_workInfoHomepage: http://www.librecat.org/personId=43C61214-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-5013-2843 bibo_doi: 10.1021/acsenergylett.0c02448 bibo_issue: '2' bibo_volume: 6 dct_date: 2021^xs_gYear dct_identifier: - UT:000619803400036 dct_isPartOf: - http://id.crossref.org/issn/2380-8195 dct_language: eng dct_publisher: American Chemical Society@ dct_title: Exploiting the lability of metal halide perovskites for doping semiconductor nanocomposites@ ...
