Abstract:
1. A process for forming a nanostructure comprising: providing a metal to a reaction chamber, wherein the metal is provided to the reaction chamber as a metal layer formed on a surface; heating the reaction chamber to a reaction temperature, the reaction temperature being greater than the melting point of the metal such that the metal layer becomes molten, wherein the reaction temperature is between 650° C. and about 1500° C.; flowing a first vapor stream comprising a first reactant through the reaction chamber; and reacting the molten metal in the layer with the first reactant at the reaction temperature and ambient pressure via a process consisting of a thermal chemical vapor deposition reaction process to form a first reaction product comprising the metal and the first reactant, wherein the first reaction product exhibits low solubility and low wetting characteristics with respect to the molten metal in the layer; and forming a nanowire or a nanobelt comprising the first reaction product.
