Ultrafast extrinsic spin-Hall currents
arXiv:cond-mat/0606725 · doi:10.1016/j.ssc.2006.07.009
Abstract
We consider the possibility of ultrafast extrinsic spin-Hall currents, generated by skew scattering following the optical injection of charge or pure spin currents. We propose a phenomenological model for this effect in quantum well structures. An injected charge current leads to a spin-Hall-induced pure spin current, and an injected pure spin current leads to a spin-Hall-induced charge current. The resulting spin or charge accumulation can be measured optically.
