Abstract: A method of fabricating a composite field emission source is provided. A first stage of film-forming process is performed by using RF magnetron sputtering, so as to form a nano structure film on a substrate, in which the nano structure film is a petal-shaped structure composed of a plurality of nano graphite walls. Afterward, a second stage of film-forming process is performed for increasing carbon accumulation amount on the nano structure film and thereby growing a plurality of nano coral-shaped structures on the petal-shaped structure. Therefore, the composite field emission source with high strength and nano coral-shaped structures can be obtained, whereby improving the effect and life of electric field emission.

Abstract: A field emission display device and a method of fabricating the same are provided. The field emission display device includes a substrate, a transparent cathode layer, an insulation layer, a gate electrode, a resistance layer, and carbon nanotubes. The transparent cathode layer is deposited on the substrate. The insulation layer is formed on the cathode layer and has a well exposing the cathode layer. The gate electrode is formed on the insulation layer and has an opening corresponding to the well. The resistance layer is formed to surround the surface of the gate electrode and the inner walls of the opening and the well so as to block ultraviolet rays. The carbon nanotube field emitting source is positioned on the exposed cathode layer. An alignment error between the gate electrode and the cathode is removed, and carbon nanotube paste is prevented from remaining during development, thereby preventing current leakage and short circuit between the electrodes and diode emission. Accordingly, the performance of the field emission display device can be improved.

Each particle has a layer of electrically insulating material (222, 232) disposed either in a first location between the conductive surface of the substrate (221) and the particle (223), or in a second location between the particle (231) and the environment (237) in which the field electron emission material is disposed, but not in both of such first and second locations, so that at least some of the particles (223, 231) form electron emission sites at such first or second locations. A number of field emission devices are disclosed, utilizing such electron emission material.

Abstract: To create a field electron emission material, there is printed upon a substrate (1501) an ink (1503) comprising a major component of fluid vehicle; a first minor component of electrically insulating material, either on its own or provided within a precursor therefor; and a second minor component of electrically conductive particles (1504). The printed ink is then treated to expel the major component and create the field electron emission material from the minor components on the substrate. The electrically conductive particles may be omitted, to print a solid, electrically insulating layer in a field emission device.
