Abstract: Apparatus and method are provided for using a multi-element field emission cathode in a color cathode ray tube. The field emission cathode may have from four to ten field emission arrays linearly arranged. The arrays are preferably formed from carbon-based material. An electron gun assembly focuses electron beams from each array on to a phosphor stripe or dot on the screen of the cathode ray tube. Deflection apparatus moves the beam from each field emission array according to clock signals. Clock signals also turn on or turn off voltage to contacts controlling electron current from the array. Values of voltage applied, determined by a video signal, determine the intensity of electron current from each array, which controls the intensity of the light emitted by each color stripe or dot of phosphor on the phosphor screen.

Abstract: A method for fabricating a triode field emitter array using carbon nanotubes having excellent electron emission characteristics is provided. In the method for fabricating a triode-structure carbon nanotube field emitter array, a catalyst layer is formed on a cathode electrode without forming a base layer, and carbon nanotubes are grown on the catalyst layer using a Spind't process. In this method, a non-reactive layer is formed on a catalyst layer outside the micro-cavity such that the carbon nanotubes can be grown only on the catalyst within the micro-cavity. Accordingly, even though a separation layer is etched and removed, since carbon nanotubes do not exist outside the micro-cavity, it does not happen that carbon nanotubes are drifted into the micro-cavities. Therefore, the fabrication yield is increased, and the fabrication cost is decreased.

Preferably, the surface of the diamond substrate is a {100} face, and the diamond protrusion is surrounded by {111} faces.

Abstract: An electron field emission device is provided by placing a substrate in a reactor, heating the substrate and supplying a mixture of hydrogen and a carbon-containing gas at a concentration of about 8 to 13 per cent to the reactor while supplying energy to the mixture of gases near the substrate for a time to grow a first layer of carbon-based material to a thickness greater than about 0.5 micrometers, subsequently reducing the concentration of the carbon-containing gas and continuing to grow a second layer of carbon-based material, the second layer being much thicker than the first layer. The substrate is subsequently removed from the first layer and an electrode is applied to the second layer. The device is free-standing and can be used as a cold cathode in a variety of electronic devices such as cathode ray tubes, amplifiers and traveling wave tubes. The surface of the substrate may be patterned before growth of the first layer to produce a patterned surface on the field emission device.

Abstract: In a method of manufacturing a field emission cold cathode which has an emitter chip (25) of a metal material on a conductive layer (21) and is placed in a predetermined vacuum, a protection film (26) is formed on the emitter chip to prevent an unfavourable layer from being formed directly on the emitter chip. The protection film is removed from the emitter chip at a time when the field mission cold cathode is placed in the predetermined vacuum. On the conductive layer, an insulation layer (22) and a gate electrode layer (23) are formed to define a cavity (24). In the cavity, the emitter chip is formed on an exposed surface (21a) of the conductive layer.
