  • Patent number: 7404980
    Abstract: The inventive method relates to microelectronic and consists in the application of an emission layer to elements of an addressable field-emission electrode with the aid of a gas-phase synthesis method in a hydrogen flow accompanied by a supply of a carbonaceous gas. A dielectric backing is made of a high-temperature resistant material and discrete elements of the addressable field-emission electrode are made of a high-temperature resistant metal. The growth rate of the emission layer on the dielectric backing is smaller than the growth rate of the emission layer on the metallic discrete elements as a result of a selected process of depositing the carbonaceous emission layer, namely the backing temperature, the temperature of the reactor threads, the pumping speed of a gas mixture through the reactor, a selected distance between the reactor threads and the backing and a settling time. The cathode metallic discrete elements can be made of two metallic layers.

  • Publication number: 20040071876
    Abstract: A method is provided for growing diamond films on substrates for formation of cold cathodes having high electron emission at a low electric field. High and uniform electron emission properties are obtained by growing the film in a hot filament reactor and in proximity to the surface of a heated grid made of graphite or other selected materials. The grid temperature is in the range of about 800° C. to about 2000° C. Mixtures of hydrogen and carbon-containing gases are used to forms the diamond.

  • Publication number: 20030143321
    Abstract: The inventive method relates to microelectronic and consists in the application of an emission layer to elements of an addressable field-emission electrode with the aid of a gas-phase synthesis method in a hydrogen flow accompanied by a supply of a carbonaceous gas. A dielectric backing is made of a high-temperature resistant metal. The growth rate of the emission layer on the dielectric backing is smaller than the growth rate of the emission layer on the metallic discrete elements as a result of a selected process of depositing the carbonaceous emission layer. For producing a display structure, a control grid is obtained from the metal layer having an emission threshold higher than a field density at which the cathode emits the required current. The inventive method enables to avoid operations of removing the emission layer making it possible to produce flat displays having high characteristics in addition to high performance and low cost.

  • Patent number: 6593683
    Abstract: The present invention relates to the production of highly efficient films for field-effect electron emitters, wherein said films may be used in the production of flat displays, in electronic microscopes, in microwave electronics, in light sources as well as in various other applications. This invention more precisely relates to a cold cathode that comprises a substrate having a carbon film applied thereto. The carbon film has an irregular structure consisting of carbon micro-ridges and/or micro-threads which are perpendicular to the surface of the substrate, have a size ranging typically from 0.01 to 1 microns and a distribution density of between 0.1 and 10 &mgr;m2. This invention also relates to method for producing a cold electrode, wherein said method comprises generating a DC current discharge in a mixture comprising hydrogen and a carbon-containing additive, and further depositing the carbon phase on the substrate located at the anode.

  • Patent number: 6577045
    Abstract: The present invention may be used in the production of highly efficient films for electron field emitters. The cold-emission cathode of the present invention comprises a substrate having a carbon film with an irregular structure applied thereon. This structure comprises carbon micro- and nano-ridges and/or micro- and nano-threads which are perpendicular to the surface of the substrate, which have a typical size of between 0.005 and 1 micron as well as a distribution density of between 0.1 and 100 &mgr;m−2, and which are coated with a diamond nano-film whose thickness represents a fraction of a micron. The method for producing the cathode involves sequentially depositing two carbon films. A carbon film with nano-barbs is first deposited on a substrate arranged on an anode by igniting a direct-current discharge at a density of between 0.15 and 0.5 A.

  • Patent number: 6509701
    Abstract: The present invention may be used in the field of microelectronics, in medicine as well as in the production of lighting appliances. The method and the device of the present invention are used for increasing the brightness of optical radiation sources powered by low-voltage power supplies. The optical radiation is generated by emitting electrons and by exciting the radiation. The electrons are generated by emitting the same from the surface of a cathode, while the excitation of the radiation involves accelerating the electrons in the gaseous interval up to an energy exceeding the excitation energy of the radiating levels of the gas. To this end, a voltage is applied between the cathode and the anode, wherein said voltage does not exceed the ignition voltage of a self-maintained discharge. The device of the present invention comprises a chamber as well as electrodes having surfaces which are transparent to the radiation.
