    摘要: 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. This method is characterized in that the discharge is generated at a current density of between 0.15 and 0.5 A/cm2. The deposition process is carried out in a mixture containing hydrogen and vapors of ethylic alcohol or methane, under an overall pressure of between 50 and 300 Torrs and at a substrate temperature of between 600 and 900° C. The concentration of ethylic alcohol vapors ranges from 5 to 10% while that of methane vapors ranges from 15 to 30%. This invention also relates to another method for producing a cold cathode, wherein said method comprises generating a microwave discharge at an absorbed power of between 100 and 1000 W. This discharge is generated in a mixture containing gaseous carbon oxide as well as methane in an 0.8-1.2 concentration and under a pressure of between 10 and 200 Torrs, the carbon phase being further deposited on the substrate. This method is characterized in that the deposition process is carried out at a temperature on the substrate surface that ranges from 500 to 700° C.

    摘要: 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. The gas pressure inside the chamber is determined from balance conditions between the energetic length of an electron trip and the distance between said electrodes.
