Effect of laser energy and substrate temperature on the optical and structural characteristics of ZnO: Cu thin film

Using the pulsed laser deposition method, thin films of (ZnO 3%Cu) were prepared, and the effects of laser energy at (600, 700, 800 MJ) and substrate temperature at (200, 300, 400 °C) on the structural and optical Characteristics were investigated. The nature of the deposited films and crystal size...

Description
Summary:Using the pulsed laser deposition method, thin films of (ZnO 3%Cu) were prepared, and the effects of laser energy at (600, 700, 800 MJ) and substrate temperature at (200, 300, 400 °C) on the structural and optical Characteristics were investigated. The nature of the deposited films and crystal size were measured by X-ray diffraction analysis (XRD). In this study, the surface morphology and roughness of the thin films were determined using atomic force microscopy (AFM). The thickness of the films was determined using an (Ellipsometer). The value of the optical energy gap was determined by using the UV-VIS spectroscopy technique. The crystallographic findings are supported by FESEM measurements. Using an energy-dispersive X-ray spectroscopic technique, it was shown that Cu ions were effectively incorporated into the lattice of the (ZnO) nanostructure without affecting its wurtzite structure.
