Patents by Inventor Mark Levendorf

Mark Levendorf has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9947749
    Abstract: Certain embodiments of the present invention include a versatile and scalable process, “patterned regrowth,” that allows for the spatially controlled synthesis of lateral junctions between electrically conductive graphene and insulating h-BN, as well as between intrinsic and substitutionally doped graphene. The resulting films form mechanically continuous sheets across these heterojunctions. These embodiments represent an element of developing atomically thin integrated circuitry and enable the fabrication of electrically isolated active and passive elements embedded in continuous, one atom thick sheets, which may be manipulated and stacked to form complex devices at the ultimate thickness limit.
    Type: Grant
    Filed: November 13, 2014
    Date of Patent: April 17, 2018
    Assignee: Cornell University
    Inventors: Jiwoong Park, Mark Levendorf, Cheol-Joo Kim, Lola Brown
