A theory is suggested for the description of luminescence in semiconductor structures, with the essential role of localized states caused by disorder. The theory is based on the set of rate equations. In contrast to most previous theoretical studies, electrons and holes are treated not in the form o...

Zusammenfassung:A theory is suggested for the description of luminescence in semiconductor structures, with the essential role of localized states caused by disorder. The theory is based on the set of rate equations. In contrast to most previous theoretical studies, electrons and holes are treated not in the form of excitons but rather as independent species. Theoretical results are compared with new experimental data for the time-resolved photoluminescence in GaInNAs/GaAs quantum wells.
