本文研究了具有非对称量子化势的准二维系统在平行于结构平面的磁场中电子与声学声子的相互作用。它表明，在这样的系统中的电子-声子相互作用产生电动势时，有一个驻声波，以及当结构被均匀加热。这些现象是普遍量子效应的宏观表现，这相当于由任何电子系统的任何各向同性扰动产生的电动势，其中能量不对称地取决于速度ε，即，ε（ε）<$ε（− ε）。
This paper studies the interaction of electrons and acoustic phonons in a quasi-two-dimensional system with an asymmetric quantizing potential in a magnetic field that is parallel to the structure’s plane. It is demonstrated that the electron-phonon interaction in such a system generates an emf when there is a standing acoustic wave, as well as when the structure is heated uniformly. These phenomena are macroscopic manifestations of a universal quantum effect, which amounts to an emf being generated by any isotropic perturbation of any electron system in which the energy depends asymmetrically on the velocity υ, i.e., ε(υ)≠ε(−υ).
