| Abstract(in English) | A distribution graph of electronic potential and track near cathode microtip in FFEA was obtained by finite difference simulating three dimensions for texture of double gate FFEA. It is clearly a result that electrons focusing effect becomes stronger as the focus electrode bias decreases toward the tip potential. If negative focusing electrode bias, we may affirm that the electronic lens repels almost all electrons and finally return to the grid electrode. The potential of gate electrode almost dose not affect the trajectories of electrons from microtip by the quantum tunneling metal cathode, which can only increase electronic amount as voltage applied gate become more higher. The electrons that are of bigger shooting angle will be embarrassed as diameter of focus electrode reduce. |
