Density-dependent thermopower oscillations in mesoscopic two-dimensional electron gases

We present thermopower S and resistance R measurements on GaAs-based mesoscopic two-dimensional electron gases as functions of the electron density n _s . At high n _s we observe good agreement between the measured S and S _MOTT , the Mott prediction for a non-interacting metal. As n _s is lowered,...
