Abstract
A semiconductor cathode is realized with the aid of a pin structure in which the intrinsic semiconductor region includes a first region with a small band distance and a second region with a large band distance. Consequently, at a sufficient reverse voltage, electrons (6) are generated in the first region (6) which electrons tunnel from the valence band to the conduction band and have a sufficient potential energy to be emitted from the semiconductor body.
