Abstract

The electronic structures of the nearly optimally doped single-layer, bilayer and trilayer Bi-based cuprates are investigated by angle-resolved photoemission spectroscopy. A lineshape analysis of data taken for different photon energies indicates that the interlayer coupling within the trilayer is not stronger than its counterpart in the bilayer system. This suggests that the higher T_c of the trilayer cuprate superconductors is not due to an enhancement of the coupling strength between the neighboring CuO₂ planes within each unit cell.
