Abstract
A photonic electron emission device includes an emitter, a photonic energy conduit evanescently coupled to the emitter, and an anode. The emitter includes a component selected from the group consisting of a metal, a semimetal, a semiconductor having a bandgap that is less than about 3.5 eV. The anode is positively biased with respect to the emitter, the anode directing electrons emitted from the emitter.
