Summary:9 Semiconductor device for generating an electron current. A semiconductor cathode is realized with the aid of a pin structure in which the intrinsic semiconductor region (5, 6) comprises a first region (6) with a small. band distance and a second region (5) with a large band distance. Consequently, at a sufficient reverse voltage electrons (13) 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 (1).
