  • Diamond film growth argon-carbon plasmas
    Patent number: 5849079
    Abstract: A method and system for manufacturing diamond film. The method involves forming a carbonaceous vapor, providing a gas stream of argon, hydrogen and hydrocarbon and combining the gas with the carbonaceous vapor, passing the combined carbonaceous vapor and gas carrier stream into a chamber, forming a plasma in the chamber causing fragmentation of the carbonaceous and deposition of a diamond film on a substrate.
    Type: Grant
    Filed: April 4, 1995
    Date of Patent: December 15, 1998
    Assignee: The University of Chicago
    Inventors: Dieter M. Gruen, Alan R. Krauss, Shengzhong Liu, Xianzheng Pan, Christopher D. Zuiker
  • Diamond film growth from fullerene precursors
