Abstract
The interaction of surface acoustic waves with a two-dimensional electron system is investigated on heterojunctions at low temperatures () and high magnetic fields (≤ 10 T). Surface acoustic waves are propagated through the heterojunction containing a high-mobility two-dimensional electron gas and situated between the emitting and receiving transducers. The interaction between the two-dimensional electron system and the surface acoustic wave produces strong quantum oscillations in the sound attenuation and the sound velocity which can be quantitatively explained.
