Light Induced Hall effect in semiconductors with spin-orbit coupling
arXiv:cond-mat/0605159 · doi:10.1103/PhysRevB.76.085343
Abstract
We show that optically excited electrons by a circularly polarized light in a semiconductor with spin-orbit coupling subject to a weak electric field will carry a Hall current transverse to the electric field. This light induced Hall effect is a result of quantum interference of the light and the electric field, and can be viewed as a physical consequence of the spin current induced by the electric field. The light induced Hall conductance is calculated for the p-type GaAs bulk material, and the n-type and p-type quantum well structures.
