| 英文摘要 | The asymmetric spin distribution in k space caused by the pure spin current (psc) can introduce a photoexcited charge current (pecc). this provides us a practical scheme for direct detection of psc. we demonstrate theoretically that the pecc related to the psc depends sensitively on the wave vector and spin orientation of the carriers, more important, the helicity dependence of this pecc provides us a way to refine it from the helicity independent background current by tuning the polarized laser beams from left to right circular polarization.
