Synthesis and Characterization of Zinc Selenide Thin Films by Vacuum Deposition Technique

Abstract

Materials of Group II-VI of the periodic table are very suitable for electronics and optoelectrical applications. Zinc Selenide (ZnSe) is one of them. The thin film of ZnSe has been grown on a cleaned glass substrate by vacuum deposition technique under a vacuum 10-6 Torr. The zinc selenide powder is heated in a molybdenum boat at 600°C. The substrates temperatures were maintained constant during deposition. The Zinc Selenide (ZnSe) thin films prepared by vacuum evaporation method were investigated. The crystal structure and lattice parameter ZnSe thin films are determined by X-ray diffractograms. X-rays diffraction measurement confirms the cubic structure of ZnSe thin film. The lattice parameters of deposited ZnSe thin films are almost matching with the JCPDS standard data of zinc selenide. The surface morphology of ZnSe thin film was investigated by SEM analysis.
