The structure of Si(111) √7×√7 R19.1°-Co reconstructed surface have been investigated by scanning tunneling microscopy (STM). Three proposed sites on the reconstructed surface, the Co atom site, the cap-adatom site and the bridge-adatom site have been all visualized by STM. The electric structure at each adatom site was measured by scanning tunneling spectroscopy, exactly. The reason why the bridge site can be visualized under the restricted condition is also explained by the local electric state above the Fermi level.
