Abstract

In this article we present results of an investigation the PL properties of highly Si &dgr;-doped GaAs/AlAs multiple QWs at liquid nitrogen and room temperatures. We discuss possible mechanisms for carrier recombination in the QW structures placing particular emphasis on the origin of the low energy tail in the PL spectra, and its features.
