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."}],"author":[{"id":"38DB5788-F248-11E8-B48F-1D18A9856A87","last_name":"Katsaros","first_name":"Georgios","full_name":"Georgios Katsaros"},{"last_name":"Golovach","first_name":"Vitaly","full_name":"Golovach, Vitaly N"},{"first_name":"Panayotis","full_name":"Spathis, Panayotis N","last_name":"Spathis"},{"last_name":"Ares","full_name":"Ares, Natalia","first_name":"Natalia"},{"last_name":"Stoffel","full_name":"Stoffel, Mathieu","first_name":"Mathieu"},{"last_name":"Fournel","full_name":"Fournel, Frank","first_name":"Frank"},{"last_name":"Schmidt","first_name":"Oliver","full_name":"Schmidt, Oliver G"},{"first_name":"Leonid","full_name":"Glazman, Leonid I","last_name":"Glazman"},{"last_name":"De Franceschi","first_name":"Silvano","full_name":"De Franceschi, Silvano"}],"doi":"10.1103/PhysRevLett.107.246601","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/1107.3919"}],"_id":"1755","title":"Observation of spin-selective tunneling in sige nanocrystals","quality_controlled":0,"citation":{"ista":"Katsaros G, Golovach V, Spathis P, Ares N, Stoffel M, Fournel F, Schmidt O, Glazman L, De Franceschi S. 2011.
