Abstract
From angle-resolved photoemission measurements on the annealed Ge(111)c?(hy(2×8) surface, detailed dispersions are presented for two previously reported surface-state bands. Additional surface states dispersing between these bands are observed. The resulting surface-state dispersions show similarities with recently observed surface-state bands on the annealed Si(111)7×7 surface and with metal-adatom-induced surface states on Si(111). It is suggested that a similar adatom bonding mechanism may be present on these surfaces.Keywords
