ABSTRACT:
A field emission electron emitter employing a coating of diamond material disposed on a surface of a layer of conductive/semiconductive material is constructed by a method including the steps of implanting carbon ions at a surface of a selectively shaped substrate to function as nucleation sites for the diamond formation. A conductive layer is deposited over the diamond and the substrate is removed to leave an electron emitter with a diamond coating.
