GROWTH CHARACTERIZATION OF CdZnS THIN FILM PREPARED BY CHEMICAL BATH DEPOSITION
نویسندگان
چکیده
Ternary semiconductor CdZnS films were prepared by chemical bath deposition (CBD). Effect of Zn concentration and deposition time on the forming chaarcterization of CdZnS films are investigated by the optical transmission spectra. The competition mechanism of Zn and Cd with the complexing agent NH3 to forming the complex play a critical role in the forming of Cd1-xZnxS thin film when Zn concentration is low, while the integrated rate of Zn into the film only increase with the increase of Zn concentration. Effect of the deposition time on forming process of the CdZnS film was also discussed. The result shows that the rate of Cd integrated into CdZnS system is rapider than the rate of Zn during the growth process of CdZnS thin films with the increasing of the deposition time.
