我们利用实际的杂质散射模型，在经典输运理论中计算了存在周期势的二维电子气体的磁电阻率。由周期光栅中回旋轨道的几何共振引起的磁振荡，称为Weiss振荡，被证明受到传统半导体异质结构中主要的小角散射过程的强烈影响。我们的结果与实验结果完全一致。
We calculate the magnetoresistivity of a two-dimensional electron gas in the presence of a periodic potential within classical transport theory, using realistic models of impurity scattering. The magneto-oscillations induced by geometric resonance of the cyclotron orbits in the periodic grating, known as Weiss oscillations, are shown to be affected strongly by the small-angle scattering processes dominant in conventional semiconductor heterostructures. Our results are in full agreement with experimental findings.
