Problems solved by technology

However, due to the addition of the gate, the side effect is that the overall device structure becomes complicated, and the manufacturing process of the overall device becomes unsimplified.

The currently developed three-pole structure devices generally have disadvantages such as high gate voltage and complicated manufacturing process, and many researchers still need to conduct a lot of research

In addition, the manufacturing process and shape of the carbon nanotube cathode are also responsible for the high gate voltage.
