摘要:

我们报告了电子-电子相互作用对物理观测量(电导等)的影响的详细研究。双量子阱异质结构中的无序电子液体。我们发现,即使在两个量子阱中的电子的共同弹性散射的情况下,在量子阱中的电子-电子相互作用的不对称性和内部在低温下使他们困惑。我们的研究结果与最近的量子阱Al $_x$ Ga $_{1-x}$ As/GaAs/Al $_x$ Ga $_{1-x}$ As异质结的输运实验定量一致。

英文摘要:

We report a detailed study of the influence of the electron-electron interaction on physical observables (conductance, etc.) of a disordered electron liquid in double quantum well heterostructure. We find that even in the case of common elastic scattering off electrons in both quantum wells, the asymmetry in the electron-electron interaction across and within quantum wells decouples them at low temperatures. Our results are in quantitative agreement with recent transport experiments on the gated double quantum well Al$_x$Ga$_{1-x}$As/GaAs/Al$_x$Ga$_{1-x}$As heterostructures.
