  • Method of producing a nanotube layer on a substrate
    Patent number: 7033650
    Abstract: In a method of producing a nanotube layer on a substrate by using a CVD process, the substrate is placed in a reaction chamber, which is flushed with a carbon-containing gas. Subsequently, the substrate is heated by an induction process to a temperature at which carbon from the gas phase is deposited on the substrate while forming nanotubes thereon.
    Type: Grant
    Filed: March 20, 2002
    Date of Patent: April 25, 2006
    Assignee: Electrovac, Fabrikation, Elektrotechnischer Spezialartikel, Gesellschaft mbH
    Inventors: Klaus Mauthner, Xinhe Tang, Roland Haubner

  • Method of depositing a polycrystalline diamond layer on a nitride substrate
    Patent number: 5925413
    Abstract: A method of depositing a polycrystalline diamond layer on a nitride substrate is disclosed, which comprises chemically-etching the nitride substrate with a KOH or NaOH solution or melt and depositing the polycrystalline diamond layer on the nitride substrate from a vapor phase, wherein the etching temperature, time and concentration of the etchant are controlled so that at least 75% of the interface between the substrate and the diamond layer is covered by diamond crystals, each diamond crystal having a contact area with the substrate of .gtoreq.20 um.sup.2.
