Effects of Percentage of the Volume of the Electrolyt on CdO Thin Films Growth by Using Electro Deposition Method Under Magnetic Field

This work presented that percentage of the volume of the electrolyte effect on CdO thin films obtained by electrodeposition. The crystal properties were investigated by using an X-Ray diffractometer (XRD). The XRD results showed that polycrystalline structures of CdO were formed which have cubic face form. Besides, the dislocation densities, crystallite sizes and micro strains were calculated via XRD results. It is observed that when percentage of the volume of the Cd(NO3)2 was decreased, the intensity of the films diffraction peaks were increased. The energy band gaps of the samples were varied from the 2.56 to the 2.16 depends on increasing annealing temperature. The surfaces of the CdO samples were analyzed SEM photographs and these photographs showed that there are striated like CdO structure, CdO nanocrystalline grains along with some spongy clusters and CdO nanocrystalline grains on the surfaces of some films. Moreover, the spongy clusters were decreased as CdCl2 volume in the final solution was reduced.
