Abstract
Zinc telluride (ZnTe) thin films were sublimated on a glass substrate using closed space sublimation (CSS) technique. The influence of the substrate temperature on the physical properties is studied. The deposited films were immersed in AgNO 3 solution with different concentrations, and then annealed in air. The structure and composition are studied using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). X-ray diffraction patterns of as-deposited ZnTe thin films exhibited polycrystalline behavior. The preferred orientation of (1 1 1) having cubic phase irrespective of the substrate temperature was observed. The XPS analysis confirmed the presence of Ag in the ZnTe thin films after doping by immersion in the AgNO 3 solution of different concentrations. [ABSTRACT FROM AUTHOR]
