Abstract

Thin films of p-CuO has been synthesized using a simple electrochemical technique (Galvanic deposition) on Indium Tin Oxide (ITO) coated glass substrates and on ZnO/ITO coated glass substrates. The films were characterized using X-ray Diffraction Technique (XRD) and UV–VIS spectroscopy. The surface morphology of the films was studied using FESEM. Measurements of electrical properties of the n-ZnO/p-CuO heterojunction were carried out to understand its suitability for gas sensing application.
