Effect of Zn:Se Ratio on the Properties of Sprayed ZnSe Thin Films

Abstract

The effect of Zn:Se ratio on the photoconducting properties of ZnSe thin films has been studied. The ZnSe thin films have been deposited onto glass substrates by the spray pyrolysis method, the substrate temperature kept at 430 C using mixed aqueous solutions of ZnCl 2 and SeO 2 with different Zn:Se ratios. Their electrical, structural, and photoconductivity properties have been studied. The values of optical bandgap have been determined from the absorption spectra.
