Abstract
The interface of a binary single quantum-well (SQW) structure of ZnSe/CdSe, where CdSe less than one monolayer is sandwiched by ZnSe layers (submonolayer SQW), is characterized by photoluminescence spectroscopy. The dependence of the energy, linewidth, and intensity of excitonic emission from submonolayer SQWs on the well thickness of CdSe is extensively investigated. The characteristics of the excitonic emission are interpreted in terms of alloy formation at the interface.Keywords
