Effect of electron drag by phonons on the thermopower of a semiconductor quantum well with Pöschl-Teller confining potential


The thermopower in a semiconductor quantum well with a confining Pöschl-Teller potential is calculated taking into account the drag of electrons by phonons. On the basis of the obtained theoretical results, the temperature dependence of thermopower in a GaAs / AlxGa1-x As quantum well at low temperatures has been studied. Numerical calculations show that our theoretical results are in good agreement with experimental ones. This indicates that the Pöschl-Teller potential satisfactorily describes the confinement potential in semiconductor quantum wells.

Keywords: quantum hole, Pöschl-Teller potential, thermoelectric motive force.
PACS: 73.50 Lw; 73.63 Hs
