  • Patent number: 10762925
    Abstract: A patterned magnetic graphene made from the steps of transferring or growing a graphene film on a substrate, functionalizing the graphene film, hydrogenating the graphene film and forming fully hydrogenated graphene, manipulating the extent of the hydrogen content by using an electron beam from a scanning electron microscope to selectively remove hydrogen, wherein the step of selectively removing hydrogen occurs under a vacuum, and forming areas of magnetic graphene and non-magnetic graphene. A ferromagnetic graphene film comprising film that has a thickness of less than two atom layers thick.
    Type: Grant
    Filed: October 10, 2018
    Date of Patent: September 1, 2020
    Assignee: The Government of the United States of America, as represented by the Secretary of the Navy
    Inventors: Woo K. Lee, Keith E. Whitener, Paul E. Sheehan
