磁场作用下垂直流于横向势垒的二维脏电子系统中电流的巨振荡
Giant oscillations of the current in a dirty 2D electron system flowing perpendicular to a lateral barrier under magnetic field
摘要：
本文从理论上研究了在磁场作用下存在横向势垒的二维脏电子系统中的电荷输运。穿过势垒的量子隧穿提供了位于其两侧的边缘态的量子干涉，这导致垂直流向横向结的充电电流的巨大振荡。我们的理论分析与参考文献8中的实验观察结果吻合得很好。特别是，电导最大值的位置与朗道能级重合，而电导本身即使在共振隧穿发生的能量下也基本上被抑制，因此这些令人困惑的观察结果可以在不考虑电子-电子相互作用的情况下得到解决。
英文摘要：
The charge transport in a dirty 2-dimensional electron system biased in the presence of a lateral potential barrier under magnetic field is theoretically studied. The quantum tunneling across the barrier provides the quantum interference of the edge states localized on its both sides that results in giant oscillations of the charge current flowing perpendicular to the lateral junction. Our theoretical analysis is in a good agreement with the experimental observations presented in Ref.8. In particular, positions of the conductance maxima coincide with the Landau levels while the conductance itself is essentially suppressed even at the energies at which the resonant tunneling occurs and hence these puzzling observations can be resolved without taking into account the electron-electron interaction.
