An electron device including a diamond material electron emitter and an anode, both disposed on a supporting substrate, so as to define an interelectrode region therebetween. Electron transport across the interelectrode region is initiated at an emitting surface of the diamond material electron emitter. An alternative embodiment employs a gate electrode disposed substantially symmetrically and axially displaced about the electron emitter and substantially in the interelectrode region to provide a modulation capability.
