  • Diamond on nanopatterned substrate
    Patent number: 11634834
    Abstract: A method for growing polycrystalline diamond films having engineered grain growth and microstructure. Grain growth of a polycrystalline diamond film on a substrate is manipulated by growing the diamond on a nanopatterned substrate having features on the order of the initial grain size of the diamond film. By growing the diamond on such nanopatterned substrates, the crystal texture of a polycrystalline diamond film can be engineered to favor the preferred <110> orientation texture, which in turn enhances the thermal conductivity of the diamond film.
    Type: Grant
    Filed: August 24, 2021
    Date of Patent: April 25, 2023
    Assignee: The Government of the United States of America, as represented by the Secretary of the Navy
    Inventors: Karl D. Hobart, Tatyana I. Feygelson, Marko J. Tadjer, Travis J. Anderson, Andrew D. Koehler, Samuel Graham, Jr., Mark Goorsky, Zhe Cheng, Luke Yates, Tingyu Bai, Yekan Wang
