抄録

The electronic energy-band properties of epitaxially grown YBa2CuO3O7-x(001) single-crystal thin films have been investigated by angle-resolved ultraviolet photoemission spectroscopy (ARUPS) with synchrotron radiation as the light source. The (001) surfaces exhibit sharp (1×1) low-energy electron-diffraction patterns. Our ARUPS data show a clear Fermi edge and dispersive nature of the valence bands, suggesting the validity of the band concept for this oxide. We determined energy-band dispersion along the directions in the bulk Brillouin zone. The experimental results are compared with the existing ground-state band calculations.
