ABSTRACT

CdSe ultra thin films were deposited by using DC electro deposition technique on mirror glass substrate in non-aqueous bath. The preparative parameters were optimized to get good quality CdSe thin films. X-ray diffraction analysis of the deposited films showed the presence of polycrystalline nature with Hexagonal phase. Temperature effect also observed that the deposition potential decreases with increase in the bath temperature. The surface morphology studies by SEM show that the deposited film is well adherent & grains are uniformly distributed over the surface of substrate. Optical absorption study showed that CdSe films were of direct band gap type semiconductor with band gap energy of 1.70 eV
