| Abstract: | It is shown that a homogeneous nonequlibrium spin polarization in semiconductor hetero- structures results in an electric current. The microscopic origin of the effect is an inherent asymmetry of spin-flip scattering in systems with lifted spin degeneracy caused by k-linear terms in the Hamiltonian. |
| Keywords: | optical orientation spin relaxation spin-flip scattering |
