Abstract

We have performed a systematic high energy (7-11 meV) and momentum (0.01 angstrom^-1) resolution angle-resolved photoemission spectroscopy (ARPES) on superstructure-free Bi_1.80Pb_0.38Sr_2.01CuO_6-δ with various dopings. All the samples from overdoped T_c = 0K to underdoped T_c = 18K possess a large hole-like Fermi surface centered at X point, whose volume shows a systematic evolution with doping. The superconducting gap exhibits a d_x(2)-y(2)-like anisotropy with a typical gap value of 10-15 meV. By comparing with Bi₂Sr₂CaCu₂O₈, we found that the size of superconducting gap and the ARPES spectral feature near E_F are well scaled with the maximum T_c (T_c^max). This suggests that the superconducting properties are characterized by T_c^max irrespective of the number of CuO₂ layers or the structural modulation in BiO layer.
