(Institut Català de Nanociència i Nanotecnologia) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia) ; Valenzuela, Sergio O. (Institut Català de Nanociència i Nanotecnologia)
We generalize the diffusive model for spin injection and detection in nonlocal spin structures to account for spin precession under an applied magnetic field in an anisotropic medium, for which the spin lifetime is not unique and depends on the spin orientation. [...]

(Institut Català de Nanociència i Nanotecnologia) ; Valenzuela, Sergio O. (Institut Català de Nanociència i Nanotecnologia)
A large enhancement in the spin-orbit coupling of graphene has been predicted when interfacing it with semiconducting transition metal dichalcogenides. Signatures of such an enhancement have been reported, but the nature of the spin relaxation in these systems remains unknown. [...]

9 p, 997.0 KB Giant spin lifetime anisotropy in graphene induced by proximity effects / Cummings, Aron W. (Institut Català de Nanociència i Nanotecnologia) ; Garcia, José H. (Institut Català de Nanociència i Nanotecnologia) ; Fabian, Jaroslav (Universität Regensburg. Insitute for Theoretical Physics) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia)
We report on fundamental aspects of spin dynamics in heterostructures of graphene and transition metal dichalcogenides (TMDCs). By using realistic models derived from first principles we compute the spin lifetime anisotropy, defined as the ratio of lifetimes for spins pointing out of the graphene plane to those pointing in the plane. [...]

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. [...]

(California Institute of Technology. Jet Propulsion Laboratory) ; Chang, Y. -C. (University of Illinois at Urbana-Champaign. Department of Physics) ; American Physical Society
We present a device concept for a spintronictransistor based on the spin relaxation properties a two-dimensional electron gas(2DEG). The device design is very similar to that of the Datta and Das spin transistor. [...]
