摘要：

We have identified the adatom contribution in the Ge 3d core-level spectra from the clean Ge(111)c (2 X 8) surface, shifted 0. 17 eV to higher binding energy compared to the bulk. This adatom component vanishes in the Ge(111)-Sn(7 X 7) surface core-level spectra where Sn occupies the adatom site. Moreover we report the observation of an earlier proposed difference between the rest atoms in the c (2 X 8) structure, and also a shift to lower binding energy for the rest atoms in both structures studied.
