Growth of Copper Telluride Thin Films using Electrodeposition

Copper Telluride thin films have been prepared on Fluorine doped Tin Oxide coated conducting glass substrates using electro-deposition technique. Cyclic voltammetric analysis has been carried out to analyze the growth mechanism of the deposited films. Thickness value of the deposited films has been estimated using Stylus profilometry. X-ray diffraction pattern revealed that the prepared films possess polycrystalline in nature. Microstructural parameters such as crystallite size, strain and dislocation density are evaluated using observed X-ray diffraction data. Optical absorption analysis showed that the prepared films are found to exhibit band gap value around 2.03 eV.
