Abstract
Magneto-oscillations have, for the first time, been observed in the thermal conductance of GaAs/AlGaAs heterostructures containing two-dimensional electron systems. The oscillations result from a modulation of the thermal-phonon lifetime via coupling to the Landau-quantized electrons confined in quantum wells near the sample surface. These thermal-conductance measurements provide a new avenue for study of both the high-field density of states and the electron-phonon interaction in these semiconductor systems.
