Structural Analysis of CdO2(1-X) AlX Thin Films Prepared by Pulsed-Laser Deposition

In this study, CdO2 (1-X) AlX thin films were prepared by pulsed-laser deposition. The X-ray diffraction patterns reveal that the films were polycrystalline with a cubic structure, and the composition of the material changed from CdO at the target to CdO2 in the deposited thin films. The intensity of the diffraction peak (or the texture factor) decreases with increasing hkl and has a maximum value for the (111) plane, the interplanar distance and diffraction angle has a high deviation from the standard value for the (111) plane and. This deviation is affected by doping concentration and shows its highest deviation at a doping concentration of 0.1 wt.% for the (111) and (200), and the 0.3 and 0.5 wt.% for the (210) and (220) planes, respectively. The crystalline size take a less value at plane has a high texture factor that is (111) plane and decreases with increase the doping concentration.
