ABSTRACT

The electron tunneling through a non-stationary tunnel barrier is investigated within an approximation of low amplitude of a variable electric field. The usability conditions of applicability of a mode of the single-quantum transition through a non-stationary potential barrier are specified. The density dependence of a high-frequency electron current through a barrier on the frequency and the applied direct bias voltage is considered. It is shown that the active part of the high-frequency electron current density can be negative at the over-barrier electron passage through a barrier.
