Abstract

The phonon drag contribution S(gxx) to the thermopower is calculated for a 2DEG by using Boltzmann equations for both electrons and phonons. The system has a parabolic confining potential and is subjected to an in-plane magnetic induction field B and the temperature gradient is parallel to B. A quasi-phonon model is proposed which greatly simplifies the calculation of S(g). Qualitative comparison is made between the theoretical predictions and experimental data.
