Abstract
Different substrate temperature of CdZnTe films and one with Al-induced crystallization have been investigated by XRD, AFM and UV-spectrophotometry. It was shown that, as the substrate temperature varied from room temperature to 400 °C, improving the substrate temperature helps to enhance the grain size of CdZnTe film, and favours the preferential orientation (111). Moreover, Al-induced crystallization method can effectively reduce the crystallization temperature of the CdZnTe film so that the film can be for high-quality oriented crystallization in a lower temperature. In addition, Al-induced crystallization can make the surface roughness of the film at a small value that facilitates the later application of the film.
