摘要：

We report temperature-dependent angle-resolved photoemission spectroscopy (ARPES) on superstructure-free Bi1.80Pb0.38Sr2.01CuO6-delta (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 (<pi>,0)-(pi,pi) cut, indicating a holelike Fermi surface centered at (pi,pi). 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.
