Fatmah Bahabri some Structural and Morphological Properties of ZnS Thin Films Structural and Morphological Properties of ZnS

Abstract

ABSTRACT: We have prepared and characterized Zinc Sulfide ZnS thin films with different thickness and have studied the effects of both thickness variations and annealing processes on the structural and morphological properties of ZnS thin films, which grown by conventional thermal evaporation technique were investigated. Both ZnS powder and the obtained films, with different thicknesses, have been subjected to XRD analysis. We have remarked that the powder possesses (110) orientation (at room temperature). Even, when annealing at 300°C, 500°C for 1 h, we have noticed that the powder maintains this orientation. However, the thin films possess (111) and (104) orientation.  After SEM and AFM, we have noticed the presence of some homogeneous grains. The grains size and the surface roughness value have increased with both the thin film thickness and the annealing temperature.
