Abstract
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.
Claims14
An electron device comprising:
- a supporting substrate having a major surface;
- a diamond material electron emitter disposed on a part of the major surface of the supporting substrate and having an emitting surface for emitting electrons;
- and
- an anode, for collecting at least some of any emitted electrons, disposed on a part of the major surface distally with respect to the emitting surface of the diamond material electron emitter and defining an interelectrode region therebetween.
