Abstract:
Ultrasharp diamond edges and points which are usable as high intensity point sources for the emission of electrons, ions, X-rays, coherent and incoherent light and high frequency electromagnetic radiation are produced by preparing and classifying ultrafine diamond powder having a particle size of 10 to 100 angstroms, placing the powder in a diamond mold defining the ultrasharp edge or point to be produced and applying a pressure of the order of 80 to 90 kb while heating the powder to a temperature of the order of 2440.degree. K. in an ultrahigh vacuum or inert atmosphere after degasing to avoid oxidation of the diamond powder.
Abstract:
A field emission cathode comprising a cathode base composed of carbon or a high-melting-point metal and a needle-shaped cathode composed of glassy carbon, which can provide a high field emission stably even under a high vacuum pressure, and a method for the preparation of this field emission cathode.

PROBLEM TO BE SOLVED: To provide a field emission element containing a thermally conductive film of integrated circuit package, a low-k dielectric layer of integrated circuit multilevel wiring, a heat conductive adhesion film, a heat conductive film of thermoelectric cooling element, a passivation film for integrated circuit elements (ICs) and a field-emission cathode. SOLUTION: A diamondoid includes a low-class diamondoid, a recently provided high class diamondoid, and substituted and non-substituted diamondoid. The diamondoid containing material may be processed as a polymer containing diamondoid, a sintered ceramics containing diamondoid, a diamondoid-ceramic complex, a CVD diamondoid film, a self-assembled diamondoid film, and a diamondoid-fullerene complex. The system paves the way for new applications of the diamondoid containing material in microelectronics. COPYRIGHT: (C)2009,JPO&INPIT
