Abstract = {We report the first experimental demonstration that phonon drag is present in the thermopower of a two-dimensional electron gas at a GaAs-Ga0.68Al0.32As heterojunction in both zero and high magnetic fields. The experiment involves polishing the rear surface of the GaAs plate on which the junction is grown in order to increase the phonon mean free path. This results in an increase of the thermopower by about a factor of 2 even though the electrical resistivities are unaffected. {\copyright} 1988 The American Physical Society.},
