Study the structural and optical properties of CuO thin films prepared by d.c magnetron sputtering

Abstract EN

In this research (CuO) films were prepared onto glass substrate of glass using plasma magnetron sputtering technique.

the results of XRD showed that the thin films had a polycrystalline structure with monoclinic lattice unit cell.

the roughness of the prepared films were identified by atomic force microscope (AFM), where the results showed that the roughness increased from (0.386-4.22)nm with increasing the thickness from(95-316)nm.

optical properties of the prepared films of (335-1135) nm showed that the absorption of the films decreased with increasing of wavelength for all thicknesses, optical energy gap for the prepared films decreased from (3.15-2.8)eV with increasing thickness from (95-316)nm.
