Abstract
We report PL studies of the kinetics or current-induced non-equilibriu m Landau level (LL) populations in 2DEGs. The B-2 field dependence of the relaxation rate is inconsistent with theoretical rates for one- an d two-phonon inter-LL processes, suggesting relaxation takes place by extrinsic processes.
