Abstract

Using illustrative examples from the investigations of the author and his collaborators, it is shown that (1) piezo-modulated reflectivity (2) photoluminescence and (3) Raman spectroscopy can be effectively used in the study of collective and localized excitations in semiconductor heterostructures. Results on epilayers of Cd1-xMnxTe:In and ZnSe and quantum well structures of GaAs/AlxGa1-xAs; Cd1-xMnxTe/Cd1-yMnyTe; Cd1-xMnxTe/CdTe; Cd1-xMnxTe:In/CdTe are discussed.
