摘要：
The localization in a disordered metal by means of the perturbation approach is considered. It is shown that in the case of a given impurity potential a small disorder leads to localization in 2D as well as in 1D and causes the weak localization in 3D. In contrast, in the case of the impurity potential screened by electrons (interacting electrons) the disorder effect on polarizability can significantly be suppressed by the Coulomb vertex corrections to the bare impurity vertex as shown. The application of the results to 1D-3D and layered 2D cases are discussed. (C) 1997 Elsevier Science Ltd.
