Studying the Effect of Doping in Some Physical Properties of Copper Oxide Thin Film

Abstract

Thin films of pure copper oxide and doped copper oxide have been prepared bychemical spray pyrolysis. The films were doped with Manganese (Mn) by 2% & 4%ratios. X-ray diffraction show that all prepared films have The two strong peaks of theCuO films appear at 35.74o and 38.95o which correspond to diffraction from planes(-111) and (111) respectively. The absorption coefficient was calculated fromtransmission spectra range (450 – 950 nm) , the absorption coefficient increase bydoping, the allowed direct optical band gab energy has been evaluated from absorptioncoefficient and the energy band gab increased by doping.
