Abstract

We have performed a systematic angle-resolved photoemission spectroscopy on the high-Tc superconducting family of Bi2Sr 2Can-1CunO2n+4 (n=1-3). We find that large Fermi surface and d-wave superconducting gap are the generic features of Bi-family high-Tc cuprates. Comparison of the nodal dispersion in the superconducting state shows that the kink in energy dispersion becomes more pronounced with increasing layer number n, indicating stronger coupling between electrons and a collective mode.
