论文摘要
我们通过强大的高频电磁场驱动的潜在屏障来开发弹性电子隧穿的理论。证明驱动的屏障可以被视为固定的两台势势，其中包含限制在这两个障碍之间的准平台电子状态。当入射电子的能量与准平稳状态的能量重合时，驱动的屏障变得完全透明（谐振隧穿）。开发的理论用于描述通过电磁波照射的量子接触的电子传输。
We developed the theory of elastic electron tunneling through a potential barrier driven by a strong high-frequency electromagnetic field. It is demonstrated that the driven barrier can be considered as a stationary two-barrier potential which contains the quasi-stationary electron states confined between these two barriers. When the energy of an incident electron coincides with the energy of the quasi-stationary state, the driven barrier becomes fully transparent for the electron (the resonant tunneling). The developed theory is applied to describe electron transport through a quantum point contact irradiated by an electromagnetic wave.
