Linear defects on Cu(111): The appearance and disappearance of surface states
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 Γ point is obtained atom...

| Sumario: | 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 Γ point is obtained atom by atom. We also report on one- and two-dimensional defect states lying near the Fermi level. |
