Abstract
Zinc oxide (ZnO) nano-wires have draw people's attention in recent studies. The unique structural and physical properties offer fascinating potential for future technological applications. The state-of-the-art fabrication process of ZnO nano-wires is based on vapor-liquid-solid (VLS) method. In this paper, the microwave assisted heating technique is introduced for the growth of ZnO nanopillar arrays. The microwave grown ZnO nanowires were characterized by fieldemission scanning electron microscopy, X-ray diffraction, transmission electron microscopy, and photoluminescence spectroscopy. It was demonstrated that (001) oriented single crystal ZnO nanowires can be grown vertically and uniformly on a-plane sapphire wafers.
