Abstract

The photoluminescence spectra of GaAs/AlGaAs multiple-quantum-well structures with varying thicknesses have been studied as a function of excitation intensity and polarization. An intense sideband luminescence with a narrow linewidth is observed at 36 meV below the band-to-band transition in all samples. These results, along with additional investigations detailed in this paper, support the conclusion that for the samples studied in these experiments this emission is a stimulated phonon-assisted recombination.
