摘要：

The paper deals with the deposition of Cu2Se/ZnSe/Cu2Se sandwich structure using facile thermal evaporation and the impact of sequential annealing on the characteristics of sandwich structure. XRD reveals the polycrystalline nature of sandwich structures. Laser Raman was carried out to explore the crystalline phase of sandwich structure. SEM analysis shows good crystalline nature with well-distinguished particles over the ZnSe layer. Cross-sectional FESEM image confirms the merged layer with no distinguished separate monolayers. Photoluminescence emission spectra of films exhibit violet emission and blue shifts upon annealing. Shifts and splits in optical bandgap values were observed upon annealing. Hall measurements infer p-type conductivity for the sandwich structure.
