The origin of magnetism in wide-gap semiconductors doped with non-ferromagnetic 3d transition metals still remains intriguing. In this article, insights in the magnetic properties of ordered mesoporous Cu-doped SnO₂ powders, prepared by hard-templating, have been unraveled. [...]

4 p, 673.6 KB Resonant interband tunneling spin filter / Ting, David Z. -Y. (California Institute of Technology. Jet Propulsion Laboratory) ; Cartoixà Soler, Xavier (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; American Physical Society
We propose an InAs/GaSb/AlSb-based asymmetric resonant interband tunnelingdiode as a spin filter. The interband design exploits large valence band spin-orbit interaction to provide strong spin selectivity, without suffering from fast hole spin relaxation. [...]

4 p, 695.9 KB Bidirectional resonant tunneling spin pump / Ting, David Z. -Y. (California Institute of Technology. Jet Propulsion Laboratory) ; Cartoixà Soler, Xavier (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; American Physical Society
We propose a mechanism for achieving bidirectional spin pumping in conventional nonmagnetic semiconductorresonant tunnelingheterostructures under zero magnetic field. The device is designed specifically to take advantage of the special spin configuration described by the Rashba effect in asymmetric quantum wells. [...]
