Structural and Optical Properties of Cd0.4 Se0.6 Thin Films Prepared by CBD

Cd0.4 Se0.6 thin films have been prepared on a glass substrate by chemical bath deposition( CBD) technique. AFM and X-ray analysis were utilized to investigate the effect of thickness variation on surface morphology and crystallinty. The optical properties of thin films were also investigated as a function of film thickness, which was noticed to be improved with the increasing of film thickness. This could be attributed to the fact that films thinner than 400 nm are under strain which decreases as the film thickness increases
