Surface, Electron and Ion Emission


The limiting field-emission current of a nanographite film cathode is studied experimentally. The maximal field-emission current density reaches 1 A/cm2. Experimental data agree with numerical estimates based on the general theory of field emission with regard to features inherent in nanostructured carbon materials.
