摘要：

The magnetic freeze-out of two-dimensional electrons (the formation of a Wigner crystal or disordered dielectric state) is shown to stimulate acoustical- and optical-phonon emissions in the course of their radiative recombination with an acceptor-bound hole. This allows us to expect an appearance of the corresponding phonon replicas in the spectra taken at the long time-delayed tail of the time-resolved magnetoluminescence in low-density GaAs-AlxGa1-xAs heterostructures in extreme magnetic fields.
