Problems solved by technology

On the other hand, if the macroscopic shape of the carbon nanotube cathode is changed and the curvature becomes smaller, it can also form a large enough electric field at a lower gate voltage to force the carbon nanotubes to emit electrons, thus indirectly reduces the operating voltage of the gate
