  • Patent number: 9005407
    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 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-like 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-like structures on the petal-like structure. Therefore, the composite field emission source with high strength and nano coral-like structures can be obtained, whereby improving the effect and life of electric field emission.

  • Patent number: 7641884
    Abstract: Disclosed is a method of fabricating carbon nanotubes and carbon nano particles, the method comprising: providing a plurality of carbon micro carriers on a silicon substrate; forming a plurality of carbon nano particles on the carbon micro carrier by a first gas; and reacting with a second gas to provide a plurality of carbon nanotubes. Thus the carbon nanotube can be formed without the use of a metal catalyst. The carbon nanotubes can easily separate from each other without the problem of non-uniformity, because the carbon micro carrier used is in a microscale size.

  • Publication number: 20090085457
    Abstract: A field emission cathode and a method for manufacturing the same are disclosed. In the present invention, the carbon nanotube is coated with an amorphous coating material so that the above-mentioned field emission cathode resists oxidization in a high electrical field and the structure thereof can be protected. Additionally, the field emission cathode can exhibit field emission performance in a low electrical field, and generate stable current as the electrical field increases so that the efficiency and stability of the field emission current can be enhanced.
