ABSTRACT:
A cathode structure is formed by a process in which a carbon-containing electron-emissive cathode is subjected to electronegative atoms that include oxygen and/or fluorine. The cathode is also subjected to atoms of electropositive metal, typically after being subjected to the atoms of oxygen and/or fluorine. The combination of the electropositive metal atoms and the electronegative atoms enhances the electron emissivity by reducing the work function.
