STUDY OF THE STRUCTURAL, OPTICAL AND ELECTRICAL PROPERIES OF PBO: CDO THIN FILM AT ROOM TEMPERATURE

In this research, pulse laser deposition Nd:YAG has 1064 nm wavelength, with a number of 400 shoots, was used to produce (PbO:CdO) thin films with different ratio (0.1, 0.3 , 0.5, 0.7 and 0.9) atom at room temperature under vacuum. The films were examined by UV-Visible spectroscopy, X-ray diffraction and Atomic force microscope to study the effect of film ratio on it properties. It was found that the absorption decrease with increasing CdO ratio from 3.5 to 0.7 at 600 nm, while the energy gap increase from 2.6 to 2.9 eV with it. Electrical properties show enhance the films conductivity with increasing CdO ratio and convert from P-type to n-type at 0.5 PbO:CdO thin films ratio.
