The data show the states' energies and strengths to be strongly dependent on position in the unit mesh. Implications of this for structural models of the 7×7 superlattice are discussed.en-USReal-Space Observation of Surface States on Si(111) 7×7 with the Tunneling MicroscopeJournal Article2016-11-1810.1103/PhysRevLett.55.2032
