Abstract

We report on the effects of substrate temperature and RF power on the formation of aligned nanorods in ZnO thin films. ZnO thin films were sputter-deposited in mixed Ar and N2 gas ambient at various substrate temperatures and RF power. At low substrate temperatures (below 300°C), ZnO nanorods do not form regardless of RF power. High RF power helps to promote the formation of aligned ZnO nanorods. However, lower RF power usually lead to ZnO films with better crystallinity at the same substrate temperatures in mixed Ar and N2 gas ambient and therefore better photoelectrochemieal (PEC) response.
