Growth of GaN nanowires by using a vapor-liquid-solid (VLS) mechanism with Pt catalysts was investigated. Single-crystal GaN nanowires with diameters of ∼100 nm and lengths of ∼5 μm were grown with Pt and with the well-known VLS catalyst of Ni. The growth rate of nanowires with Pt was lower than that with Ni under identical processing conditions. Pt-Ga alloy globules were observed by Transmission electron microscopy at the ends of the nanowires which lead the growth by the VLS mechanism. Electrical data from individual nanowires indicated high conductivity associated with high electron concentration in the Pt-GaN nanowires.
