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.
