Abstract
An improved field emission device (200, 800) includes a supporting substrate (210, 810), a conductive layer (215, 815) formed on the supporting substrate (210,810), a dielectric layer (240, 840) formed on the conductive layer (215, 815) and defining an emitter well (260, 860), a charge bleed-off barrier (290, 890)provided on the lateral surfaces (245, 845) of the emitter well, an electron emitter (270, 870) located within the emitter well (260, 860), a gate extraction electrode (250, 850) formed on the dielectric layer (240, 840) and spaced from the electron emitter (270, 870), and an anode (280, 880) spaced from the gate extraction electrode (250, 850).
