Research Abstract |
We investigated emission uniformity from the planar cathodes based on nc-Si prepared by pulsed Nd : YAG laser ablation. Distributions of electron emission showed strong dependence on thin metal morphology. The emission occurred at limited parts of the emission area for the cathode with discontinuous metal and the whole for the cathode with continuous metal due to series resistance effects. Continuity and conductivity of thin metal film are important for uniform and high directional emission from the planar cathodes.
