摘要：

We propose a phenomenological theory of the acoustoelectric drag effect. The electric current dragged by the surface acoustic wave is shown.to possess the unusual shape of the Shubnikov-de Haas oscillations. Namely, the drag-current component along the wave propagation direction has an oscillating sign and passes through zero near both sigma(xx) minima and maxima, whereas the perpendicular (i.e., Hall) component oscillates similarly to the diagonal conductivity.
