The surface states of Bi 2Γx Pb x Sr 2 CaCu 2 O 8ΓΎy (Pb-Bi-2212, x ΒΌ 0:6) single crystals are investigated by scanning tunneling microscopy/spectroscopy in order to clarify the origin of inhomogeneous superconducting states. The topography obtained at a cleaved surface of Pb-Bi-2212 showed the coexi
