Abstract

We report high-resolution angle-resolved photoemission spectroscopy on single-layered cuprate superconductor (Bi,Pb)₂(Sr,La)₂CuO_6+δ as a function of temperature and doping level, to elucidate the origin of shadow band (SB). We found that the intensity of SB is invariable with respect to temperature, doping, and substitution constituents of block layers, indicating that antiferromagnetic correlation is not responsible for the emergence of SB. Observation of similar SB in Bi₂Sr₂CaCu₂O_8+δ and La_1.85Sr_0.15CuO₄, but not in YBa₂Cu₃O_7-δ further supports the structural origin of SB.
