中文摘要	We have performed a systematic doping-dependent angle-resolved photoemission spectroscopy (ARPES) of Pb-substituted Bi2201 (Bi1.80Pb0.38Sr2.01CuO6-delta) With high energy (7-11 meV) and momentum (0.01 Angstrom (-1)) resolutions. We found that all the samples show a large hole-like Fermi surface centered at (pi,pi), whose volume changes systematically as a function of doping. The superconducting gap exhibits a d(x2-y2)-like anisotropy with a typical gap value of 10-15 meV near (pi ,0). By comparing with Bi2Sr2CaCu2O8 (Bi2212), we found that the size of superconducting gap is well scaled with the maximum T-c (T-c(max)) Doping-dependence of spectral line shape at (pi ,0) is very similar between Bi2201 and Bi2212, while its energy scale is different by a factor of 4, corresponding to the ratio of T-c(max) between the two compounds. These indicate that the superconducting and pseudogap properties are characterized by T-c(max) irrespective of the number of CuO2 layers or the BiO superstructure. (C) 2000 Elsevier Science Ltd.
