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.

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.

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.
