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 ...
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 ...
