Abstract
A conducting 1D chain or 2D film inside (or on the surface of) an insulator is considered. Impurities displace the charges inside the insulator. This results in a long-range fluctuating electric field acting on the conducting line (plane). This field can be modeled by that of randomly distributed electric dipoles. This model provides a random correlated potential with <U(r)U(r+k)> \propto 1/k. In the 1D case such correlations may essentially influence the localization length but do not destroy Anderson localization.
