The lack of Anderson transition in high-resistance alloys with a high electron density V.F. Gantmakher
For three-dimensional electron systems with a high electron density, one cannot attain the Anderson transition either by enhancing disorder, or by combining static and dynamic disorders (by high temperature), or by choosing a material with large deformation potential and large electron-fonon interaction constant. PACS: 72.15.Rn Localization effects (Anderson or weak localization); 71.23.An Theories and models; localized states. Keywords: Anderson localization, conductivity of alloys.
