Effect of substrate on electroplated copper sulphide thin films

Abstract

Copper Sulphide thin films have been prepared on different substrates using electrodeposition technique. X-ray diffraction analysis showed that the prepared films possess polycrystalline in nature with cubic structure. Microstructural parameters such as crystallite size, strain and dislocation density are determined using X-ray diffraction data. Film composition and surface morphology have been analyzed using Scanning electron microscopy and Energy dispersive analysis by X-rays. Optical absorption analysis showed that the prepared films possess band gap value in the range between 2.2 and 2.4 eV for films obtained on different substrates.
