Abstract

We have performed a systematic doping-dependent angle-resolved photoemission spectroscopy (ARPES) of Pb-substituted Bi2201 (Bi_1.80Pb_0.38Sr_2.01CuO_6-δ) 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 (π,π), whose volume changes systematically as a function of doping. The superconducting gap exhibits a d_x(2)-y(2)-like anisotropy with a typical gap value of 10-15 meV near (π,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 (π,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.
