{"status":"public","abstract":[{"lang":"eng","text":"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."}],"_id":"1755","day":"07","main_file_link":[{"url":"http://arxiv.org/abs/1107.3919","open_access":"1"}],"acknowledgement":"The work was supported by the Agence Nationale de la Recherche (through the ACCESS and COHESION projects), U.S. DOE Contract No. DE-FG02-08ER46482 (Yale), and the Nanosciences Foundation at Grenoble, France.
