Resumen:
The appearance and disappearance of the Shockley surface state on Cu(111)is studied as a function of density and width of extended adsorbed defects using a Hamiltonian that contains s, p, and d orbitals in the basis. The local electronic density of the surface state at the G point is obtained atom by atom. We also report on one- and two-dimensional defect states lying near the Fermi level.
