Abstract: An amorphous diamond electrical generator having a cathode at least partially coated with amorphous diamond material and an intermediate member coupled between the cathode and an anode. The amorphous diamond material can have at least about 90% carbon atoms with at least about 20% of the carbon atoms bonded in a distorted tetrahedral coordination. The amorphous diamond coating has an energy input surface in contact with a base member of the cathode and an electron emission surface opposite the energy input surface. The electron emission surface can have an asperity height of from about 10 to about 1,000 nanometers and is capable of emitting electrons upon input of a sufficient amount of energy. The intermediate member can be coupled to the electron emission surface of the amorphous diamond coating such that the intermediate member has a thermal conductivity of less than about 100 W/mK and a resistivity of less than about 80 nullnull-cm at 20null C. The amorphous diamond electrical generator is a thermionic emission device having improved electron emission properties.

Abstract: An amorphous diamond material that is capable of emitting electrons in a vacuum upon the input of a sufficient amount of energy is disclosed. The material may utilize both compositional and geometrical aspects in order to maximize electron output and minimize required energy input. In one aspect, the amorphous diamond material may include at least about 90% carbon atoms with at least about 30% of such carbon atoms bonded in distorted tetrahedral coordination. Further, the material may be configured with an emission surface having an asperity height of from about 10 to about 10,000 nanometers. A variety of energy types may be used separately or in combination to facilitate electron flow, such as thermal energy, light energy, and induced electric field energy. The amorphous diamond material may be incorporated into a variety of vacuum-type devices, such as switches, laser diodes, electrical generators, and cooling devices.

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.

Abstract: An electron-emitting element comprises a diamond substrate, and a diamond protrusion grown on a surface of the diamond substrate so as to have a pointed portion in a form capable of emitting an electron.

Preferably, the surface of the diamond substrate is a {100} face, and the diamond protrusion is surrounded by {111} faces.
