Comparison of exciton properties in quantum well structures of ZnCdSe/ZnSe and ZnSe/ZnMgSSe

摘要

Properties of excitons in quantum well structures of ZnCdSe/ZnSe and ZnSe/ZnMgSSe are compared. In ternary ZnCdSe quantum wells and at low Temperature excitons are strongly localised. Weaker localization is observed In quantum well structures of ZnSe/ZnMgSSe. Present studies suggest for- Mation of negatively charged excitons in the latter structures.
