--- res: bibo_abstract: - Spin-selective tunneling of holes in SiGe nanocrystals contacted by normal-metal leads is reported. The spin selectivity arises from an interplay of the orbital effect of the magnetic field with the strong spin-orbit interaction present in the valence band of the semiconductor. We demonstrate both experimentally and theoretically that spin-selective tunneling in semiconductor nanostructures can be achieved without the use of ferromagnetic contacts. The reported effect, which relies on mixing the light and heavy holes, should be observable in a broad class of quantum-dot systems formed in semiconductors with a degenerate valence band.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Georgios foaf_name: Georgios Katsaros foaf_surname: Katsaros foaf_workInfoHomepage: http://www.librecat.org/personId=38DB5788-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Vitaly foaf_name: Golovach, Vitaly N foaf_surname: Golovach - foaf_Person: foaf_givenName: Panayotis foaf_name: Spathis, Panayotis N foaf_surname: Spathis - foaf_Person: foaf_givenName: Natalia foaf_name: Ares, Natalia foaf_surname: Ares - foaf_Person: foaf_givenName: Mathieu foaf_name: Stoffel, Mathieu foaf_surname: Stoffel - foaf_Person: foaf_givenName: Frank foaf_name: Fournel, Frank foaf_surname: Fournel - foaf_Person: foaf_givenName: Oliver foaf_name: Schmidt, Oliver G foaf_surname: Schmidt - foaf_Person: foaf_givenName: Leonid foaf_name: Glazman, Leonid I foaf_surname: Glazman - foaf_Person: foaf_givenName: Silvano foaf_name: De Franceschi, Silvano foaf_surname: De Franceschi bibo_doi: 10.1103/PhysRevLett.107.246601 bibo_issue: '24' bibo_volume: 107 dct_date: 2011^xs_gYear dct_publisher: American Physical Society@ dct_title: Observation of spin-selective tunneling in sige nanocrystals@ ...
