Abstract :
The current-voltage curves of the Pt field emitters with interference patterns showed the saturation at higher applied voltage. The slope of the FN plots is also flattened at higher applied voltage. The reason for the flattened FN plots might be due to the finite reflection of ballistic electrons, when the energy barrier between the emitter and vacuum becomes lower than the Fermi energy under strong electric fields. These results indicated that the electron wave interference might take place by ballistic electrons emitted from the Pt field emitters.
