Patent ID: 8029851

Claim:
The method of fabricating nanowires with a desired diameter, the method comprising: providing catalytic nanoparticles of a size configured to produce nanowires with a desired diameter, wherein the catalytic nanoparticles comprise an inorganic particle; enclosing the catalytic nanoparticles within nanocapsules; melting the catalytic nanoparticles under reducing atmosphere; depositing the nanocapsules on a surface of a substrate; etching the nanocapsules to reveal at least part of the molten catalytic nanoparticles; supersaturating the catalytic nanoparticles with a gaseous precursor of nanowires by heating the precursor of the nanowires until the precursor decomposes and dissolves into the melted catalytic nanoparticles to saturate the catalytic nanoparticles and the precursor starts to solidify to form the nanowires after supersaturation is reached; and growing the nanowires outward from the catalytic nanoparticles by continuously supplying the precursor.
