Abstract
Vertical indium phosphide nanowires (NWs) were grown at different temperatures by metalorganic chemical vapor deposition via a gold (Au)-assisted vapor-liquid-solid mechanism. At a low growth temperature (420 °C), the lengths of the NWs were diameter independent, which indicated that the NWs were grown with significant contributions from the direct impingement of the precursors onto the alloy droplets. In this process, the droplet acts as a catalyst rather than an adatom collector. However, at a high growth temperature (480 °C), the lengths of the NWs were inversely diameter dependent. The wurtzite percentage of NWs increases with the growth temperature. Room temperature photoluminescence properties of NWs grown under different temperatures were investigated.
