Third, the control effect of the gate voltage on the carbon nanotube layer is too poor

The electron emission of part of the carbon nanotube layer can be adjusted and controlled by the gate voltage, but there is still a part of the electron emission of the carbon nanotube layer that is not controlled by the gate voltage, so that the gate voltage has a great influence on the overall carbon nanotube layer. The control ability is greatly reduced
