Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions
(APS through AIP, 2003-01/15)The density dependence of the critical in-plane magnetic field Bc at the bifurcation of the resistivity of two-dimensional electron systems with low levels of disorder is determined using the spin-polarization dependence ... -
Temperature dependent resistivity in the low-resistance region for diffusive transport in two dimensions
(APS through AIP, 2004-12/15)The interpretation of the metal-insulator transition phenomena in disordered two-dimensional electron systems in terms of density-dependent scaling variables suggests the existence of a quantum critical point at some ... -
Two-component scaling near the metal-insulator bifurcation in two dimensions
(APS through AIP, 2003-05/15)We consider a two-component scaling picture for the resistivity of two-dimensional (2D) weakly disordered interacting electron systems at low temperature with the aim of describing both the vicinity of the bifurcation and ...
