Abstract

We investigate the current-induced spin polarization in the two-dimensional hole gas with the structure inversion asymmetry, in which the orbital angular momentum is taken into account to obtain the proper generalized spin operator for the hole gas. Based on the analytical and numerical results, we find that quite different from the electron system, the spin polarization of holes depends on Fermi energy linearly in the low doping regime and has a peak once the Fermi level is between two minima of the lowest spin-split light-hole subband.
