  • Preparation of diamond and diamond-like thin films
    Patent number: 5273788
    Abstract: A layer of a hydrocarbon molecule is applied to a substrate by the Langmuir-Blodgett technique, and the surface is irradiated with a laser to decompose the layer of molecules at the surface without influencing the substrate. After decomposition the carbon atoms rearrange on the surface of the substrate to form a DLC film. The method of the invention may also be used to form other film, using a suitable molecule to produce the LB layer before irradiation.
