Title: Optical characterization of ZnO, ZnSe and ZnSe/ZnO heterostructure

Biography

Biography: Mrs. Rachida Douzi.

Abstract





ZnSe layers were grown on ZnO substrates by metal organic chemical vapor deposition technique (MOCVD). ZnO, ZnSe and ZnO/ZnSe heterostructure were investigated by Raman spectroscopy and absorption.


From the absorption spectra, we deduced the type II character of the ZnSe/ZnO heterostructure. Type II structures are very useful in photovoltaic conversion.
