Abstract

A review is presented of recent work on the logarithmic corrections due to weak localization and interaction effects in the 2D electron gas in the silicon inversion layer. It is shown that very good agreement exists between experiment and theory, and that the two logarithmic corrections can be separated by a magnetic field or a combination of magnetic and electric fields. Unlike exponential localization in a band tail, the weak (power law) localization is suppressed by a magnetic field and it is suggested that this leads to the return of a discontinuity in conductance at zero temperature, i.e. a minimum metallic conductance. It is suggested that these corrections do not have any relevance to the quantized, 2D, Hall resistance.
