Abstract: In one embodiment of the present invention, an electronic device includes a first emitter/collector region and a second emitter/collector region disposed in a substrate. The first emitter/collector region has a first edge/tip, and the second emitter/collector region has a second edge/tip. A gap separates the first edge/tip from the second edge/tip. The first emitter/collector region, the second emitter/collector region, and the gap form a field emission device.
