摘要：

The absorption of monochromatic acoustical phonons was observed by measuring the phonon-drag voltage along a two-dimensional electron gas caused in the process. From the data the existence of the 2kF cut-off is apparent which is a signature of the electron-phonon interaction in these systems. © 1990.
