  • Abstract
    Results of recent experiments with diamond-coated electron-field-emission cold cathodes are presented. The cathodes offer an almost instantaneous response to field variations and can deliver high current densities. As shown, diamond and diamond-related films deposited on the surface of a cathode significantly increase the number of emission centers and can substantially improve the homogeneity of electron emission. The emission current can be increased via increasing the sp2 graphitic phase concentration in the film.
