Abstract: A method for fabricating an electron emitter is provided. This emitter structure may be used to form individual emitters or arrays of emitters. The method is comprised of implanting energetic ions into a diamond lattice to form cones or other continuous regions of damaged diamond. These regions are more electrically conducting than the surrounding diamond lattice, and have locally sharp tips at or near the point of entry of the ion into the diamond. The tips may then also be additionally coated with a layer of a wide band-gap semiconductor. An electrically conducting material may also be placed in proximity to the tips to generate an electric field sufficient to extract electrons from the conducting tips into either the region above the surface, or into the wide band-gap semiconductor layer in contact with the tips. Electrical contact is made to the electrically conducting damage tracks and the electrical circuit may be completed with an electrically conducting material on the surface of the wide band-gap semiconductor or diamond, or in the ambient above the surface of the emitter. The surface of the wideband gap semiconductor or diamond may be chemically modified to enhance the emission of electrons from the surface.

An ohmic electrode (2) is provided on the back surface of the n-type silicon substrate (1). A direct current voltage is applied so that the surface electrode (7) becomes positive in potential relevant to the ohmic electrode (2).

Abstract: A carbon fiber for a field electron emitter has a coaxial stacking morphology of truncated conical tubular graphene layers, each of which includes a hexagonal carbon layer and has a large ring end and a small ring end at opposite ends in the axial direction. The edges of the hexagonal carbon layers are exposed on at least part of the large ring ends. Since all the exposed edges function as electron emission tips, a large amount of emission current can be obtained.

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 surface of the substrate may be patterned before growth of the first layer to produce a patterned surface on the field emission device. 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.
