Comparative Study of Synthesis of CdO-ZnO Nanocomposite Thin Films by Different Methods: A Review

Abstract

In the present work, different methods of CdO-ZnO thin films prepared on the glass substrate were compared viz. magnetron sputtering; spray pyrolysis and sol-gel techniques. The structural, optical and electrical properties of CdO-ZnO thin films were analyzed for the suitability of the material in context of stability and device formation. Among these methods, sol-gel method is best to synthesize CdO-ZnO thin films due to its low cost, easy precursors, polycrystalline nature of thin films and good approximation with optical properties.
