AB  - We use variable temperature scanning tunneling spectroscopy to determine the space and energy structure of the adatom electron band of the Si(111)-7x7 surface. At low temperature (7 K) we map the wave functions of the electrons in the adatom band in real space. We observe a pronounced splitting of the adatom electron states between corner and center adatoms of the surface reconstruction and identify new spectral features in the unoccupied part of the adatom band. The adatom electron states are subsequently identified in tunneling spectra at room temperature to obtain their energy unaffected by electron transport limitations at low temperature.
