Abstract
An emission device includes a plurality of electron emitter structures of varied geometry that have a conducting layer deposited thereon. The conducting layer has openings located at tunneling sites for each of the electron emitter structures. The tunneling sites facilitate electron emissions from each of the varied geometry electron emitter structures upon voltage biasing of the conducting layer relative to the electron emitter structures.
