We have studied low-energy electronic structure of YBa2Cu3O7-delta
using high-resolution angle-resolved photoemission spectroscopy (ARPES).
By carefully tuning photon energy and polarization of incident light,
we identified five different bands in the vicinity of the Fermi level,
those are surface-bilayer-derived bonding and antibonding bands,
their bulk counterparts, and CuO-chain-derived band, respectively.
The surface bands show metallic property reflecting highly overdoped
character, while bulk bands show signature of a dx2-y2-wave superconducting
gap opening. The present ARPES result suggests the universality of
the bulk electronic states in bilayer high-Tc superconductors.
