Influence of thermal annealing on optical properties and surface morphology of NiOx thin films
چکیده انگلیسی

NiOx thin films were deposited by reactive DC-magnetron sputtering from a nickel metal target in Ar + O2 with the relative O2 content of 5%. Thermal annealing effects on optical properties and surface morphology of NiOx films were investigated by X-ray photoelectron spectroscopy, thermogravimetric analysis, scanning electron microscope and optical measurement. The results showed that the changes in optical properties and surface morphology depended on the temperature. The surface morphology of the films changed obviously as the annealing temperature increased due to the reaction NiOx → NiO + O2 releasing O2. The surface morphology change was responsible for the variation of the optical properties of the films. The optical contrast between the as-deposited films and 400 °C annealed films was about 52%. In addition, the relationship of the optical energy band gap with the variation of annealing temperature was studied.
