Abstract: A cathode structure suitable for a flat panel display is provided with coated emitters. The emitters are formed with material, typically nickel, capable of growing to a high aspect ratio. These emitters are then coated with carbon containing material for improving the chemical robustness and reducing the work function. One coating process is a DC plasma deposition process in which acetylene is pumped through a DC plasma reactor to create a DC plasma for coating the cathode structure. An alternative coating process is to electrically deposit raw carbon-based material onto the surface of the emitters, and subsequently reduce the raw carbon-based material to the carbon containing material. Work function of coated emitters is typically reduced by about 0.8 to 1.0 eV.

Abstract: The present invention relates to an electron tube having a configuration which can maintain its operating stability for a long period of time. The electron tube comprises, at least, a field emitter which is made of diamond or a material mainly composed of diamond and has a surface terminated with hydrogen, and a sealed envelope for accommodating the diamond field emitter. Due to the hydrogen termination, the electron affinity of the diamond field emitter is set to a negative state. Also, hydrogen is enclosed within the sealed envelope. Due to this configuration, the hydrogen-terminated state of the diamond field emitter surface is stabilized, and the electron affinity of the diamond emitter is restrained from changing for a long period of time.

Abstract: A method and system for manufacturing a field emission cathode having enhanced electron emission properties. The field emission cathode is prepared by providing a field emission substrate, an alkali metal alloy is formed at and below the exposed surface of the substrate, and a surface layer of alkali metal atoms are formed on the exposed surface by Gibbsian diffusion segregation action. If the monolayer, or surface layer, is desorbed, the diffusion action reestablishes the alkali metal surface layer thereby providing a stable alkali metal layer and enhanced electron emission characteristics.
