- The (111) surface of Cu, Ag, and Au is characterized by a band of surface Shockley states with a constant density of states beginning slightly below the Fermi energy. These states as well as bulk states hybridize with magnetic impurities which can be placed above the surface. We calculate the characteristic low-temperature energy scale, the Kondo temperature TK of the impurity Anderson model, as the bottom of the conduction band Ds crosses the Fermi energy ϵF. We find simple power laws TK≃|Ds-ϵF|η, where η depends on the sign of Ds-ϵF, the ratio between surface and bulk hybridizations with the impurity Δs/Δb, and the ratio between on-site and Coulomb energy Ed/U in the model.
