Controlled Fabrication of Semiconductor-Metal Hybrid Nano-Heterostructures via Site-Selective Metal Photodeposition

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A method of synthesizing colloidal semiconductor-metal hybrid heterostructures is disclosed. The method includes dissolving semiconductor nanorods in a solvent to form a nanorod solution, and adding a precursor solution to the nanorod solution. The precursor solution contains a metal. The method further includes illuminating the combined precursor and nanorod solutions with light of a specific wavelength. The illumination causes the deposition of the metal in the precursor solution onto the surface of the semiconductor nanorods.
