Thickness effect on the structural and optical constants of stibnite thin films prepared by sulfidation annealing of antimony films

摘要: Abstract This paper deals with some physical properties of antimony sulphide Sb2S3 thin films obtained by an annealing process in sulphur vapors at 300 °C Sb thermal evaporated deposited on glass substrate. The crystal structure and surface morphology were investigated both XRD AFM techniques. structural study shows that well crystallized orthorhombic parameters such as the lattice parameter, crystallite size, microstrain degree preferred orientation have been reported correlated effect size. On other hand, refractive index extinction coefficient discussed terms Forouhi–Bloomer model. optical band gap was found to range from 1.75 2.23 eV. Finally, analysis extracted Urbach–Martienssen models lead explanations correlations between size ones.
