الوصف: We performed scanning tunneling microscopy/ spectroscopy (STM/STS) experiments to investigate Fe substitution effects on the superconductivity (SC) of overdoped Bi2212. The gap-edge peaks in STS spectrum at T≪T c become inhomogeneous strongly in Fe-doped Bi2212. The spectral weight around zero bias, namely the density of states (DOS) at ∼E F is partly recovered by substitution of Fe in every position. The recovery of the DOS at ∼E F can be explained in terms of impurity effects on d-wave SC in the unitarity limit. However, the strong inhomogeneity of gap-edge peaks would be ascribed to different effects due to Fe-substitution.
