Abstract

It is shown that optical orientation of electron spins in semiconductors can be used as a basis to develop a high-sensitivity method for measuring the dependence of the lifetime of carriers on their concentration. Experiments performed in a stationary regime on a GaAs/AlGaAs heterostructure at low excitation levels provided insight into the nonradiative recombination of electrons and holes separated by an electric field built into the interface.
