We report temperature-dependent angle-resolved photoemission spectroscopy (ARPES) on superstructure-free Bi1.80Pb0.38Sr2.01CuO6-δ (overdope, Tc<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 EF 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.
