Driving method for electric-field electron emission apparatus |
摘要 |
A method for driving an electric-field electron emission apparatus without degrading the electron emission characteristics is provided. The method can drive the electric-field electron emission apparatus without degrading the electron emission characteristics by allowing application of the electric field only when the second derivative of the captured electron current density exceeds a certain value.
