Abstract

Metal-insulator transition in anisotropic disordered Anderson model with both topological and diagonal disorder is investigated numerically. For four sets of the model parameters we found the critical disorder and the critical exponent and prove that they do not depend on the transport direction. The system size independent critical conductance distribution P_c(g) is found for each critical point. The form of P_c(g) depends on the model parameters and on the direction of the treansport. Arguments in favor of the one-parameter scaling are presented. This paper has been withdrawn
