Geometric origin of intrinsic spin hall effect in an inhomogeneous electric field

Abstract

The spin Hall effect is a transport phenomenon with significant importance for spintronics since it can be used to design ways of generating and detecting spin currents. Here, the authors investigate the intrinsic spin Hall effect induced by an inhomogeneous electric field and show that it can be engineered by tuning the Fermi energy in both Rashba and Dresselhaus systems.
