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

Thin films of pure copper oxide and doped copper oxide have been prepared by chemical 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 the CuO films appear at 35.74o and 38.95o which correspond to diffraction from planes (-111) and (111) respectively. The absorption coefficient was calculated from transmission spectra range (450 – 950 nm) , the absorption coefficient increase by doping, the allowed direct optical band gab energy has been evaluated from absorption coefficient and the energy band gab increased by doping.
