Metal-insulator transitions and the effects of electron-electron interactions in two-dimensional electron systems

Abstract

Experimental results on the metal-insulator transitions and the anomalous properties of strongly interacting two-dimensional electron systems are reviewed and critically analyzed. Special attention is given to recent results for the strongly enhanced spin susceptibility and effective mass in low-disordered silicon MOSFETs.
