The differences and superiorities of zinc oxide nanomaterials in their properties comparing with their corresponding bulk counterparts have made the nanoscience and nanotechnology come into being, which are promoting the development of each other. As the integration of the nanomaterial and a kind of wide-band semiconductor, the wide-band semiconductor nanostructures have received great attention. For example, ZnO has become the research focus including its growth methods and applications. One of the potenti...
