Abstract:
The present work reports a detailed investigation of the catalytic growth of aligned ZnO nanowires/rods through the control of parameters such as the Au catalyst layer thickness, pressure, deposition temperature, and oxygen ratio. The purpose is to achieve a controllable and reproductive process for ZnO aligned growth.<br>Overall, our work suggests that the conditions for aligned growth are basically determined by the concentration of Zn vapor on the sample and its possibility of being oxidized. A very specific amount of vapor is necessary to have the correct rate of growth, which then leads to having aligned wires. By controlling such parameters aligned nanowires/rods with different diameter and length can be grown reproducibly. The control of the aligned growth is crucial for the eminent use of ZnO nanowires in many technological applications.
