Abstract

We report temperature-dependent angle-resolved photoemission spectroscopy (ARPES) on superstructure-free Bi_1.80Pb_0.38Sr_2.01CuO_6-δ (overdope, T_c<4 K) to study the topology of the Fermi surface. The temperature dependence of ARPES spectra unambiguously shows the existence of a dispersive band that crosses E_F along the (π,0)-(π,π) cut, indicating a holelike Fermi surface centered at (π,π). We also found that the spectral intensity is strongly affected by k-dependent matrix elements but the spectral function itself suffers no photon-energy dependence.
