@article{Bernevig2005IntrinsicSH, title={Intrinsic spin Hall effect in the two-dimensional hole gas.}, author={Bogdan Andrei Bernevig and Shou-Cheng Zhang}, journal={Physical review letters}, year={2005}, volume={95 1}, pages={ 016801 } }

We show that two types of spin-orbit coupling in the 2 dimensional hole gas, with and without inversion symmetry breaking, contribute to the intrinsic spin-Hall effect. Furthermore, the vertex correction due to impurity scattering vanishes in both cases, in sharp contrast to the case of usual Rashba coupling in the electron band. Recently, the spin-Hall effect in a hole doped GaAs semiconductor has been observed experimentally by Wunderlich et al. [ Phys. Rev. Lett. 94, 047204 (2005).]. From…
