Claim Text:
1. A method for forming nanowires comprising: providing metal catalytic seed particles suspended in a gas, providing Group III and Group V gaseous precursors, that comprise constituents of the nanowires to be formed, dissolving the Group III material into the metal catalytic seed particles at a temperature of 380° C. to 700° C.; making at least one seed crystal at the surface of the at least one catalytic seed particle, and growing epitaxially at least one nanowire crystal from the at least one formed seed crystal in a gas-phase synthesis including the gaseous precursors while the catalytic seed particles are suspended in the gas and the constituents of the nanowires to be formed are supersaturated in the at least one catalyst seed particle, wherein the at least one nanowire crystal is a III-V semiconductor crystal which comprises gallium and arsenic.
