GROWTH AND CHARACTERIZATION OF Cd 1-x Zn x S FILMS BY CHEMICAL BATH DEPOSITION

Thin films of Cd1-xZnxS solid solutions are grown by the chemical bath deposition method with 0 less than or equal to x < 1. The firms are characterized by X-ray, optical and electrical measurements. X-ray studies have indicated that the films have polycrystalline nature. Optical studies have also shown that the films possess polycrystalline nature with tiny crystallites in the form of platelets. Electrical conductivity studies have revealed two activation energies in solid solutions for x 0.2 and one activation energy value for x > 0.2. The results are explained in terms of mixed hexagonal and cubic crystalline structures.
