Abstract: Cadmium oxide is the very crucial material in the field of solar cells, optoelectronic devices, flat panel displays due to its high transparency and narrow band gap. In this study, Mg doped CdO thin films were prepared using the home made spray pyrolysis unit and its structural and electrical properties were studied. The XRD results show that the grain size decreases upon increasing the dopant concentration from its broadened peak. Atomic Force Microscopy (AFM) analysis indicates that the roughness of the surface decreases upon increasing Mg concentration. The activation energy, I-V characteristics were studied using Four probe method. The results were analyzed for three different concentration of Mg doped CdO films and are reported.
