摘要：

Photocathode of CuO nanoarray (CuO NAS) with strong ability of light capture and charge separation capacity was fabricated by reactive magnetron sputtering with in-situ heating the substrate, while the phase composition, crystal morphology, crystal growth orientation, crystal face exposure, thickness and electronic structure of the films were controlled by changing oxygen partial pressure, substrate temperature, cavity pressure and sputtering time. The photocurrent density of the optimized CuO NAS photocathode is up to 2.4 mA·cm-2. © 2022, Editorial Office of Chinese Journal of Materials Research. All right reserved.
