  • Temperature dependent resistivity in the low-resistance region for diffusive transport in two dimensions 

    Geldart, D. J. W., and D. Neilson. 2004. "Temperature dependent resistivity in the low-resistance region for diffusive transport in two dimensions." Physical Review B (Condensed Matter and Materials Physics) 70(23): 235336-1. Copyright © 2004 American Physical Society.
    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 

    Geldart, D. J. W., and D. Neilson. 2003. "Two-component scaling near the metal-insulator bifurcation in two dimensions." Physical Review B (Condensed Matter and Materials Physics) 67(20): 205309-1. Copyright © 2003 American Physical Society.
    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 ...
