In addition, the electron emission of the carbon nanotube cathode needs to be strongly controlled by the grid. The shorter the distance between the grid and the cathode, the greater the electric field strength formed at the top of the carbon nanotube, and the carbon nanotube can More electrons are emitted, but at the same time, it is limited by the insulating properties of the insulating material between the gate and the cathode, and cannot cause electrical breakdown between the two
