Abstract
A device for producing an electron stream, comprising a cathode having a semiconductor body, a surface of which is coated with a material that reduces the working function of the electrons, at least part of the semiconductor body having conductivity of type p and provided with at least two electrical connections, at least one of which is an injection connection, characterized in that the coating is applied at least part of the surface of the p-type part of the semiconductor body, the coating and the part consisting of of type p in materials such that the working function of the applied coating is substantially equal to or less than the distance between the Fermi level and the lower part of the conduction band in the p-type part, so that the electrons injected in the p-type part from the injection connection can emerge through the coated surface of the p-type part, having ose means is provided to polarize the injection connection in the forward direction.
