En formet feltudstrålingselektronkilde, der anvender en diamantcoating, samt fremgangsmåde til fremstilling heraf

摘要

A field emission electron emitter employing a coating of diamond material (406) disposed on a surface of a layer of conductive/semiconductive material (407) is constructed by a method including the steps of implanting carbon ions (404) at a surface of a selectively shaped substrate (401) to function as nucleation sites for the diamond formation. A conductive layer (407) is deposited over the diamond (406) and the substrate (401) is removed to leave an electron emitter with a diamond coating.
