Abstract Electronic structure of Cu {111} surface dong Γ-K line of surface Brillouin zone (SBZ) was studied using synchrotron radiation angle-resolved photoemission. A surface state located at 3.0eV below Fermi level, near K point of SBZ was observed for the first time. It is described by localized d-electron Tamm surface state.
