ABSTRACT:
A field emission device having a diamond semiconductor electron emitter with an exposed surface exhibiting a low
egative electron affinity which is operably controlled by modulation of a junction depletion region. Application of a suitable operating voltage to a device gate electrode modulates the depletion width to control availability of electrons transiting the bulk of the electron emitter for emission at the exposed surface.
