ABSTRACT:
Depositing a diamond film on an electron emitting tip including disposing hydrocarbon and etchant reactant gasses together with the tip in a reaction vessel and providing an external voltage source such that electrons, emitted from the electron emitter, disassociate hydrocarbon constituents of the reactant gas. The constituents accelerate toward and are deposited onto the tip and are selectively etched by the etchant constituents such that only the diamond form of the deposited carbon remains.
