Abstract:
1. An amorphous diamond electrical generator comprising: a) a cathode having a base member with a layer of amorphous diamond material coated over at least a portion thereof, said amorphous diamond material comprising at least about 90% carbon atoms with at least about 20% of said carbon atoms bonded in distorted tetrahedral coordination, said diamond coating being configured with an energy input surface in contact with the base member and an electron emission surface opposite the energy input surface, said electron emission surface having an asperity height of from about 10 to about 1,000 nanometers, and being capable of emitting electrons upon input of a sufficient amount of energy into the amorphous diamond material; b) an intermediate member coupled to the electron emission surface of the amorphous diamond coating, said intermediate member comprising a material having a thermal conductivity of less than about 100 W/mK and a resistivity of less than about 80 μΩ-cm at 20° C.; and c) an anode coupled to the intermediate member opposite the amorphous diamond coating.
