Abstract
Extremely well resolved Si 2p core-level spectra from the clean Si(111 )7 X 7 surface have been obtained at similar to 100 K. Surface-shifted components become visible to the naked eye. Contributions from the co nstitutive entities of the complex 7 X 7 reconstruction, i.e., rest at oms, adatoms, pedestal atoms, and dimer atoms are clearly identified. This puts into new perspective the spectroscopy and physics (structure and electronics) of this prototypical surface.
