Growth Kinetics of Chemically Deposited CdO Thin Films

Abstract

In this work CdO films were prepared by using chemical bath depositiontechnique where the cadmium nitrate salt was used as a source of cadmium ions.The effect of different bath parameters has been considered in this work, namely,cadmium ion concentration, deposition time, temperature of solution and pH value,on the rate of deposition and terminal thickness. Annealing process in air attemperature 573K° and time of 15min. are carried out for the conversion ofcadmium hydroxide film to oxide film. X-Ray diffraction technique has confirmedthe formation of cadmium oxide (CdO).
