Abstract

Copper oxide films were grown using the pulsed laser deposition (PLD) method with either a copper metal or a copper oxide target. A variety of deposition pressures of oxygen (0.001–0.3 torr) and temperatures (350, 450, and 550°C) were explored. From x-ray diffraction analysis, epitaxial <100> CuO films were observed at 450°C and either at 0.01 or 0.1 torr for the CuO and the Cu targets, respectively. Deposition rates were measured for the two targets (Cu and CuO) as a function of laser fluence and background gas pressure and enabled a morphological study of films prepared at different laser fluences but of similar film thickness (∼0.3 μm). The number density of particulates as well as the smoothness of the underlying film surface of the CuO films varied significantly with the target composition. The CuO films from the Cu target were the smoothest and had the fewest particulates.
