A novel method of creating hot electrons via a pn junction will be used to eject electrons from a cold cathode. The accelerated electrons will have suficient energy to surmont the work function and surface dipole. The cold cathode will be used in a new type of minature Traveling Wave Tube or "Twystrode". Advanced semiconductor materials with low work functions will be produced and evaluated as planar field emitters both with and without pn junctions.
