Metal-Insulator Transition in Two Dimensions: Experimental Test of the Two-Parameter Scaling

Dmitry Knyazev

P.N. Lebedev Physical Institute Russian Academy of Sciences

We report a detailed scaling analysis of resistivity\rho(T,n) measured for several high-mobility 2D electron systems in the vicinity of the 2D metal-insulator transition. We analyzed the data using the two-parameter scaling approach and general scaling ideas. This enables us to determine the critical electron density, two critical indices, and temperature dependence for the separatrix in the self-consistent manner. In addition, we reconstruct the empirical scaling function describing a two-parameter surface which fits well the \rho(T,n) data.
