Abstract

The low-energy electronic structure of the nearly optimally doped trilayer cuprate superconductor [Formula presented] is investigated by angle-resolved photoemission spectroscopy. The normal state quasiparticle dispersion and Fermi surface and the superconducting [Formula presented]-wave gap and coherence peak are observed and compared with those of single- and bilayer systems. We find that both the superconducting gap magnitude and the relative coherence-peak intensity scale linearly with [Formula presented] for various optimally doped materials.
