| Abstract | ||
| In this research Cadmium Oxide thin films semiconductor non crystalline are deposited on substrate by chemical Spray Pyrolysis Method then it is doped by Cl than by I and in (773K) substrate temperature. The electrical characteristics study by measure the characteristics of electrical conductivity and alternating conductivity . In the case of electrical conductivity we found the relation between the conductivity and temperature after and before annealing then after and before doping also the activation energy has been calculated .we find that the increase in the conductivity happened when the temperature increase and the doping also increase it and activation energy of CdO intrinsic is about (0.631eV). Thin films of CdO which doping have conductivity decrease by increase of the temperature while the activation energy increase also. The relation between the conductivity and the frequency after and before annealing as well as after and before doping have been studied it is found that the alternating conductivity decreases when the frequency decreases , where the fast decrease happened in high frequency . However , the alternating conductivity decreases on annealing . | ||
