A Mini Review on Synthesis and Characterization of Copper Oxide Some Properties and Potential Applications

Abstract

This review focuses on the synthesis and Characterization of p-type metal-oxide (p-type CuO) semiconductor thin films, used for chemical-sensing applications. p-Type CuO thin film exhibit several advantages over n-type metal-oxide, including a higher catalytic effect, low humidity dependence, and improved recovery speed. However, the sensing performance of CuO thin film is strongly related to the intrinsic physicochemical properties of the material and their thickness. The latter is heavily dependent on synthesis techniques. Many techniques used for growing p-type CuO thin film are reviewed herein. Copper oxide is called a multifunctional material by dint of possessing a broad range of chemical and physical properties that are often highly sensitive to changes in processing parameters, although, extensive research and development, the optimization of the processing parameters are still in full development until today. Where, the overall research revealed that the different properties of copper oxide based on the experimental conditions. In this extensive review, we focus more on discussing the effect of major synthesis processing parameters such as precursor solution, annealing temperature, and thickness of the nanomaterial, which various researchers have obtained. These factors are critical overviewed, evaluated, and compared.
