  • ELECTRON GUN AND ELECTRON MICROSCOPE
    Publication number: 20230298847
    Abstract: An electron gun for an electron microscope or similar device includes a field emitter cathode having a field emitter protrusion extending from the output surface of a monocrystalline silicon substrate, and electrodes configured to enhance the emission of electrons from a tip portion of the field emitter protrusion to generate a primary electron beam. A contiguous TiN layer is disposed directly on at least the tip portion of the field emitter protrusion using a process that minimizes oxidation and defects in the TiN layer.
