Effects of Growth Time on Morphologies of ZnO Nanorod Arrays

Abstract:

well-aligned ZnO nanorod arrays (ZNRAs) grown on the ZnO seed layers coated p-silicon (p-Si) substrates in various times from 1.5 to 5 hr have been fabricated from aqueous solutions at low temperature. Morphologies, crystalline structure and optical transmission were investigated by a scanning electron microscope (SEM) and X-ray diffraction (XRD), respectively. The results showed that ZNRAs grew vertically from the substrates, having uniform thickness and length distribution, the average diameters and length of ZnO nanorods increased with increasing growth time below 3 hr. The XRD results showed that ZnO nanorods were wurtzite-structured (hexagonal) ZnO.
