Abstract

We have measured the phonon-drag thermopower of a periodically modulated two-dimensional electron gas, and report antisymmetrical commensurability oscillations developing with increasing electron density. The ballistic nature of electron transport is found to amplify the effects of transverse temperature gradients induced by anisotropy in the electron-phonon interaction.
