  • Diamond electron source having carbon-terminated structure
    Patent number: 7960905
    Abstract: The present invention provides a diamond electron source exerting stable and excellent electron emission characteristics, which can be used for a cold cathode surface structure operable with low voltage and a method for producing the diamond electron source. Specifically, the diamond electron source having a carbon-terminated structure has a structure composed of an electrode and a diamond film and emits electrons or electron beams from the diamond film when voltage is applied to the electrode. The diamond film is made of diamond having a carbon-terminated structure. The method for producing the diamond electron source is also provided herein.

  • STACKED BODY OF ISOTOPE DIAMOND
    Publication number: 20100247884
    Abstract: The present invention aims at providing a high performance device that is not restricted by the current concept of a super-lattice and can overcome or loosen limitations on physical properties of materials and various problems related to hetero junction, and achieves an isotope diamond layered body formed by layering of 12C diamond film and 13C diamond film by epitaxially growing the 12C diamond film and the 13C diamond film.
