Abstract

In a two-dimensional electron gas (2DEG) with asymmetric quantizing potential in the presence of magnetic field parallel to the 2DEG plane due to different interaction between electron system and phonons having mutually opposite directions of wave vectors the anomalous thermomagnetic effect appears. The alternating uniform heating of the crystal lattice results in emergence of alternating electromotive force. The effect is analyzed for interaction between electron system and acoustic phonons (both usual and piezoelectric) in heterojunction GaAs-AlGaAs
