  • Structure for enhancing electron emission from carbon-containing cathode
    Patent number: 5463271
    Abstract: A cathode structure contains electronegative atoms (22), which consist of oxygen and/or fluorine, chemically bonded to a carbon-containing cathode (10). Atoms (24R) of electropositive metal are chemically bonded to the electronegative atoms. The combination of the electropositive metal atoms and the electronegative atoms enhances the electron emissivity by reducing the work function.
