Interaction Between Electron and Surface Acoustic Wave
ORAL
Abstract
We probe the two-dimensional electron systems using continuous surface acoustic wave at mK-temperature. We perform thorough measurements of the acoustic wave propagation velocity as well as the acoustic current. Our result provides an intriguing access to the electron-phonon interaction.
