Supercritical Fluid−Liquid−Solid Synthesis of Gallium Phosphide Nanowires

A new GaP nanowire synthesis method is employed to produce a high yield of single crystalline wires. Reaction at 500 °C in supercritical hexane using gold seed particles results in wires that average 20 nm in diameter and tens of micrometers in length. Some wires generate twinning faults orthogonal to the wire growth direction.
