| 摘 要： | 研究了在双模电场驱动下的双量子阱系统中电子的动力学行为．利用微扰理论我们得到了耦合量子阱间的相干隧穿时间及电子局域化条件．并用数值演化方法验证了上述理论结果的正确性．这一方法可以推广到任意周期电场作用下的系统。

| Abstract: | The dynamics of an electron in two biased quantum wells driven by a dc-biehromatic electric field were investigated. By using perturbation theory, the tunneling time and the condition of localization were obtained. All those results are tested by our numerical solutions. In fact ,this method can also be applied to a system under an arbitrary periodic field. |
