  • Method for depositing diamond films by dielectric barrier discharge
    Patent number: 5776553
    Abstract: A method is disclosed for depositing diamond film, including the following steps: providing an environment comprising hydrogen gas and a hydrocarbon gas; dissociating hydrogen gas of the environment by dielectric barrier discharge to obtain atomic hydrogen; and providing a deposition surface in the environment and implementing diamond deposition on the deposition surface from the hydrocarbon gas, assisted by the atomic hydrogen. In a preferred embodiment, the atomic hydrogen is transported by molecular diffusion from its dissociation site to the deposition surface.
