Abstract

We report the synthesis of zinc oxide nanowires with unusual [101 0] growth direction via a simple chemical vapor transport method by direct oxidation of zinc powder at 850 oC. Morphology of the nanowires was characterized by field emission scanning electron microscopy. The lengths of the nanowires were up to several hundred microns and the diameters were about 100 nanometers. The growth habit of ZnO nanowires was investigated by high resolution transmission electron microscopy and selected area electron diffraction. The detail composition of ZnO nanowire was determined by X-ray energy dispersive spectrometer. This synthetic route is versatile and can be used in fabricating other one dimension metal oxide nanowires.
