Preparation and study of CdTe thin films grown by the solution method

CdTe thin films grown on glass, tin-oxide coated glass, p-Si and mica by the solution growth technique were investigated for their compositional, structural, optical and electrical properties. The films predominately show a zincblende structure when grown on glass/tin-oxide coated glass and are wurtzite when grown on p-Si and mica. Optical measurements indicate a direct band gap of 1.46 eV and an absorption coefficient of the order of 10 4 cm −1.
