  • Controlled fabrication of semiconductor-metal hybrid nano-heterostructures via site-selective metal photodeposition
    Patent number: 9834856
    Abstract: 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.
    Type: Grant
    Filed: January 4, 2013
    Date of Patent: December 5, 2017
    Assignee: Iowa State University Research Foundation, Inc.
