Abstract
Zinc oxide (ZnO) nanorods were grown on various substrates by the hydrothermal techique, and the effects of a substrate to be used on the growth of ZnO nanorods were studied. ZnO nanorods could grow vertically on a GaN but not on a Si substrate. However, they could grow on a Si substrate coated with a thick Ag film.The crystallinity and luminescence characteristic are also affected by a substrate to be used. It was also found that an array of ZnO nanorods could be formed by selective growth of ZnO on the e-beam lithographed resist pattern.
