  • Method for fabricating an electron-emissive film
    Patent number: 6290564
    Abstract: A method for fabricating an electron-emissive film (100) includes the steps of providing a powder (124), which has a plurality of carbon nanotubes (104); providing a substrate (102), a surface (103) of which defines a plurality of interstices (107); and dry spraying powder (124) onto surface (103) of substrate (102). The adjustable parameters of the dry spraying step include a separation distance of a spray nozzle (120) from surface (103), a spray angle between a spray (121) and surface (103), and a nozzle pressure at an opening (123) of spray nozzle (120). The separation distance, spray angle, and nozzle pressure are selected to achieve, for example, uniformity of electron-emissive film (100) and adhesion of carbon nanotubes (104) to substrate (102).

  • Electron emissive film and method
    Patent number: 6100628
    Abstract: A method for forming an electron emissive film (200, 730, 830) includes the steps of: (i) evaporating a graphite source (120, 620) in a cathodic arc deposition apparatus (100, 600) to create a carbon plasma (170, 670), (ii) applying a potential difference between the graphite source (120, 620) and a glass or silicon deposition substrate (130, 630, 710, 810) for accelerating the carbon plasma (170, 670) toward the deposition substrate (130, 630, 710, 810), (iii) providing a working gas within the cathodic arc deposition apparatus (100, 600), and (ii) depositing the carbon plasma (170, 670) onto the deposition substrate (130, 630, 710, 810).

  • Electron emissive film
    Patent number: 6087765
    Abstract: An electron-emissive film (170, 730) is made from graphite and has a surface defining a plurality of emissive clusters (100), which are uniformly distributed over the surface. Each of the emissive clusters (100) has dendrites (110) extending radially from a central point (120). Each of the dendrites (110) has a ridge (130), which has a radius of curvature of less than 10 nm. The graphene sheets (160) that form the dendrites (110) have a (002) lattice spacing within a range of 0.342-0.350 nanometers.

  • Method of providing uniform emission current
    Patent number: 6059627
    Abstract: A method or providing uniform emission current from a plurality of electron emitters with a composite current voltage characteristic (620), which include surface states that provide resonant tunneling emission of electrons (260). Field emission device (200) is operated beyond a decrease in the increase of emission current (630) as shown in the composite current voltage characteristic (620) in order to provide uniform emission current.
