  • Method for electrochemically depositing carbon film on a substrate
    Patent number: 8951401
    Abstract: Dense carbon films are deposited on a conductive substrate by placing the substrate acting as anode in a molten salt electrolyte bath containing a source of carbide ion and applying DC current across the substrate and a counter electrode acting as cathode also placed in the molten salt electrolyte bath. The carbide ions are electrochemically oxidized to deposit a carbon film on the surface of the substrate.
    Type: Grant

  • Method for electrochemically depositing carbon nitride films on a substrate
    Patent number: 8545688
    Abstract: Dense carbon nitride films are electrochemically formed on a conductive substrate by placing the substrate acting as cathode in a molten salt electrolyte bath and applying DC current across the substrate and a counter electrode acting as anode also placed in the molten salt electrolyte bath. Carbonate ion and nitrate ion are concurrently reduced to deposit carbon nitride films on the substrate.
