Spin transport in 3d-topological insulator nanostructures — •Matthias Stosiek, Sven Essert, Cosimo Gorini, and Klaus Richter — Institut für Theoretische Physik, Universität Regensburg, 93040 Regensburg, Germany

The spin-momentum locking for charge carriers on the surface of three-dimensional topological insulators holds promising prospects for spintronics applications. In this predominantly numerical study, we investigate the transport properties of nanostructures of 3d-TIs with ferromagnetic leads using model Hamiltonians. We also explore the influence of external electric and magnetic fields.
