Resistivity is an intrinsic feature that specifies the electrical properties of a material and depends on electron-phonon scattering near room temperature. Reducing resistivity metal to its potentially lowest value requires eliminating grain boundaries impurities, but date few studies have focused reducing pure itself. We could reduce single-crystal Ag, which has almost perfect structure, by impurity doping it with Cu. This paper presents our results: was reduced 1.35 μΩ·cm at temperature after 3 mol% Cu-doping Ag. Various mechanisms were examined in attempt explain abnormal behavior.
