Binary alloy single-crystalline metal nanostructures and fabrication method thereof

A method of fabricating a binary alloy single-crystalline metal nanostructure, comprising:

• using two substances selected from a first material to a third material separately or in a combination thereof as a precursor;
• and
• heat treating the precursor as well as a semiconductor or insulator single-crystalline substrate under inert atmosphere after placing the precursor on front part of a reaction furnace and the single-crystalline substrate on rear part of the reaction furnace to fabricate a binary alloy single-crystalline metal nanowire or nanobelt,
• wherein the binary alloy for the nanostructure includes the first material containing metal oxides, metal substances or metal halides of a metal used to form the binary alloy, a second material containing metal oxides, metal substances or metal halides of another metal used to form the binary alloy, and/or the third material containing any one of binary alloy substances for the binary alloy.
