Abstract
A device for generating an electron current for example an electronic tube having a cathode whose emission part consists of a p-type semiconductor, whose emission surface is covered with a material that reduces the electronic work function of the coating substantially equal or less than the distance from the fermi level to the lower part of the conduction band in the p-type semiconductor, the p-type semiconductor comprising an injection connection at a distance less than the electronic diffusion length in the p-type semiconductor. The emission surface, characterized in that the p-type semiconductor comprises only one electrical connection namely the injection connection, means being present for exposing the p-type semiconductor radiation which can generate free charge carriers in the p-type semiconductor .
