Web1 Introduction. When a high electric field of the order of 107 V cm −1 is applied to a solid surface with a negative electrical potential, electrons inside the solid are emitted into vacuum by the quantum mechanical tunneling effect. This phenomenon is called field emission of electrons. Such extremely high fields are obtained on the sharp ...
