Abstract

We report measurements of the thermoelectric power, S, of GaInAs-InP heterojunctions, as a function of temperature and magnetic field. For B equals O we find that S alpha 1/T below 10K, while at higher temperatures the thermopower passes through a minimum and then increases with temperature. In high magnetic fields strong oscillations of the thermopower are seen, with the same phase as the Shubnikov-deHaas oscillations in the resistivity. The thermopower at the peaks increases rapidly as the temperature is reduced, but is always less than the theoretical predictions.
