The superconducting properties of polycrystalline Sr0.6K0.4Fe2As2 were strongly influenced by Ag doping(Supercond.Sci.Technol.23(2010) 025027).Ag addition is mainly dominated by silver diffusing,so the annealing proce...
Guided by the belief that Fermi energy EF (equivalently, chemical potential μ) plays a pivotal?role in determining the properties of superconductors (SCs), we have recently derived μ-incorporated Generalized-Bardeen...
