We have studied the valence-band and surface-core-level states for thermally annealed Ge(111)-(2 × 8) and Si(111)-(7 × 7) and laser-annealed Ge(111)-(1 × 1) and Si(111)-(1 × 1) surfaces with high-resolution photoelectron spectroscopy using synchrotron radiation. We find two surface states near the top of the valence band which exhibit characteristic emission patterns within the hexagonal 1 × 1 surface Brillouin zone as well as characteristic surface-core-level spectra which indicate the existence of a common local bonding geometry for all these surfaces. © 1981 The American Physical Society.
