Intrinsic spin Hall conductivity

ORAL

Abstract

In an isotropic 2D gas with general dispersion and linear-in-k spin-orbital interaction of the Rashba or Dresselhaus type in the presence of impurities we find that an intrinsic spin-Hall conductivity is finite and is of the order of the spin-orbit term squared. It vanishes only in the well-studied particular case of a quadratic dispersion.
