Problems solved by technology

In addition, the shape of the carbon nanotube cathode will also have a certain influence on the electric field strength formed, which will indirectly lead to a somewhat high gate voltage.
For these practical problems, there is still no perfect solution, and many researchers need to seriously consider and solve them.
