A conductance in any dimensionality is reduced to a one-dimensional (1D) conductance. In an infinite system a true mobility edge appears at 2D. In a finite system a continuous change (with the Fermi energy) in the conductance dependence on the system length is determined. © 1982 The American Physical Society.
