Abstract
One of the most remarkable results of field emission (FE) quantum theory is the prediction of very high emission current densities. Very high current densities are possible due to two factors: (1) No energy is required for maintaining the emission process if electrons exit the solid by a tunneling mechanism, that is, the emitter does not need to be heated, irradiated, or otherwise excited by some external energy source; and (2) there is a very large reservoir of electrons near the Fermi level of a metal.
