Description

The quantum-mechanical problem of the motion of electrons through a potential barrier with an additional near-surface dipole layer is considered. An analytical generalization of the Fowler-Nordheim formula, for such potential barriers, was made. Using such a model is a way to consider the influence of vacancies and pores existing in the surface layer of a metal on the field emission current density. A new effect in the theory of field emission current was discovered: quantum oscillations of the current depending on the thickness of the covering layer on the metal surface or voids inside the metal surface.
