On the correlation of morphology and growth parameters in ZnO nanowires

The growth of ZnO nanowires as a function of the thickness of Au thin layers, deposition temprature and surface properties through simple carbothermal evaporation method is studied. Investigations by X-ray diffraction (XRD) revealed the (002) plane as the preferred plane for the growth of ZnO nanowires. Our experiments indicated that the temperature range of 800-900 ?C under flow of 100 sccm N2 gas with Au catalyst layer, is the suitable condition for producing the most aligned nanowires. The Vepour – Liquid - Solid (VLS) mechanism more than other mechanisms is dominant for growth process.
