The surface states of Bi 2Àx Pb x Sr 2 CaCu 2 O 8þy (Pb-Bi-2212, x ¼ 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
The crystal structure of Bi-2212 phase was studied by transmission electron microscopy. Two Bi-2212 specimens with different Sr/Ca ratios have the same displacive incommensurate Bi modulation vector q---0.21 b\*+ c\* but exhibit different superconducting critical temperatures T c. Typical structural
