  • Hydrogenated graphene with surface doping and bandgap tunability
    Patent number: 9853104
    Abstract: A graphene compound made from the method of preparing graphene flakes or chemical vapor deposition grown graphene films on a SiO2/Si substrate; exposing the graphene flakes or the chemical vapor deposition grown graphene film to hydrogen plasma; performing hydrogenation of the graphene; wherein the hydrogenated graphene has a majority carrier type; creating a bandgap from the hydrogenation of the graphene; applying an electric field to the hydrogenated graphene; and tuning the bandgap.
    Type: Grant
    Filed: April 6, 2016
    Date of Patent: December 26, 2017
    Assignee: The United States of America, as represented by the Secretary of the Navy
    Inventors: Jeffrey W. Baldwin, Bernard R. Matis, James S. Burgess, Felipe Bulat-Jara, Adam L. Friedman, Brian H. Houston
