论文摘要
我们在存在表面声波的情况下使用抛物线和线性和线性（石墨烯）分散的二维材料中的电子传输和使用半经典玻尔兹曼方程方法的外部磁场。我们观察纵向和霍尔电流的振荡行为是在固定磁场下表面声波频率的功能，并在声波的固定频率下作为反磁场的函数。我们用几何共振的现象来解释前者，而在存在声波产生的动态超级晶格的情况下，我们将后者与魏斯样振荡联系起来。因此，我们证明了二维电子气体中大气磁电效应的双重性质。
We study electron transport in two-dimensional materials with parabolic and linear (graphene) dispersions of the carriers in the presence of surface acoustic waves and an external magnetic field using semiclassical Boltzmann equations approach. We observe an oscillatory behavior of both the longitudinal and Hall electric currents as functions of the surface acoustic wave frequency at a fixed magnetic field and as functions of the inverse magnetic field at a fixed frequency of the acoustic wave. We explain the former by the phenomenon of geometric resonances, while we relate the latter to the Weiss-like oscillations in the presence of the dynamic superlattice created by the acoustic wave. Thus we demonstrate the dual nature of the acoustomagnetoelectric effect in two-dimensional electron gas.
