Investigation on the Properties of Sb-Doped CdTe Thin Films

Abstract:

Pure CdTe thin films and metal Sb-doped CdTe thin films are prepared on soda lime glass substrates by vacuum evaporation method. The prepared films have a cubic crystal structure with a preferential growth orientation along CdTe (111) crystal orientation. The experimental results show that the film surface doped Sb is more compact and uniform. And doping Sb in pure CdTe thin films significantly enhance the optical absorption and reduce the width of the band gap, which means that the optical absorption range of CdTe thin films can be widened. Finally, on the aspect of electrical properties, the resistivity of the thin films has significantly been lower.
