  • Silicon-based dielectric tunneling emitter
    Patent number: 6902458
    Abstract: An emitter has an electron supply layer and a silicon-based dielectric layer formed on the electron supply layer. The silicon-based dielectric layer is preferably less than about 500 Angstroms. Optionally, an insulator layer is formed on the electron supply layer and has openings defined within which the silicon-based dielectric layer is formed. A cathode layer is formed on the silicon-based dielectric layer to provide a surface for energy emissions of electrons and/or photons. Preferably, the emitter is subjected to an annealing process thereby increasing the supply of electrons tunneled from the electron supply layer to the cathode layer.
