摘要：
We developed a quantitative theory of the phonon-drag thermopower and the Nernst-Ettingshausen effects for the 2D electron gas in a quantum well with parabolic confinement potential in the magnetic field in the plane of the free movement of electrons. Our theoretical results are in a good agreement with experimental data [1] in the range 1-10K. In this temperature interval the main contribution to the thermopower comes from phonon-drag. Our calculations show that the temperature dependence of both the longitudinal and transverse Nernst-Ettingshausen effects is non-monotonic. We find that phonon-drag Nernst-Ettingshausen effects change sign with the temperature.
