Problems solved by technology

Of course, the macroscopic shape of the carbon nanotube cathode will also have a certain impact on the formed electric field intensity. Obviously, the smaller the curvature of the carbon nanotube shape, the easier it is to form a stronger electric field intensity. Of course, the required control The voltage will be reduced, which indirectly reduces the working voltage of the gate
