Abstract: By using a large area cathode, an electron source can be made that can irradiate a large area more uniformly and more efficiently than currently available devices. The electron emitter can be a carbon film cold cathode, a microtip or some other emitter. It can be patterned. The cathode can be assembled with electrodes for scanning the electron source.

Abstract: Differently sized silicon nanoparticles are used as a phosphor material for cathode ray tubes, field emission displays, or liquid crystal displays. The differently sized particles will emit different light wavelengths, such as red, green, and blue. Thus, the same material can be used for all three phosphors.

Abstract: Carbon nanotubes are aligned within a host phase of a material that has molecules that will align under a certain influence. When the host molecules become aligned, they cause the carbon nanotube fibers to also become aligned in the same direction. The film of aligned carbon nanotubes is then cured into a permanent phase, which can then be polished to produce a thin film of commonly aligned carbon nanotube fibers for use within a field emission device.

Abstract: Nanoparticles are coated using thick-film techniques with a catalyst to promote the growth of carbon nanotubes thereon. In one example, alumina nanoparticles are coated with a copper catalyst. Such nanoparticles can be selectively deposited onto a substrate to create a field emission cathode, which can then be utilized within field emission devices.

Abstract: A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing treatment of a substrate and then depositing the film. The treatment step creates nucleation and growth sites on the substrate for the film deposition process and promotes election emission of the deposited film. With this process, a patterned emission can be achieved without post-deposition processing of the film. A field emitter device can be manufactured with such a film.

Abstract: A cathode assembly includes a substrate (1101), a plurality of electrically conductive strips (1102), nano-size diamond particles (1701), and a layer (1801) of diamond material deposited (CVD) over the diamond particles (1701).

Abstract: A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing etching of a substrate and then depositing the film. The etching step creates nucleation sites on the substrate for the film deposition process. With this process patterning of the emitting film is avoided. A field emitter device can be manufactured with such a film. A field emission device results where the cathode has a continuous film that has not been subjected to etching, and thus has superior emission properties. A pixel in the cathode includes the emitting film deposited directly on the substrate with the conductor deposited on one or more sides of the emitter film. In one embodiment the emitter is in a window formed in the conductor layer.
