Angle-resolved photoemission from epitaxially grown YBa2Cu3O7-x (001) single-crystal thin films reveals a clear Fermi edge and fine structure near the edge. Some of the valence-band photoemission features show k-space dispersion. These new results suggest that the electronic structure of this oxide can be treated within the framework of the one-electron band picture.
