Abstract: The unexpected experimental observation
of the Metal-Insulator Transition (MIT) in Silicon MOSFETs 10 years ago
is still an outstanding problem: The existence of MIT contradicts the
commonly accepted scaling picture, where all the states are found
localized in two dimensions.
We show that the interplay of the electron-electron
interactions and disorder can explain the observed transport properties
and the anomalous enhancement of the spin susceptibility near the MIT.
