"Linear defects on Cu(111): The appearance and disappearance of surface states"
A. Barral and A.M. Llois
Phys. Rev. B 62(19) (2000) 12668-12671
The appearance and disappearance of the Schockley surface state at Cu(111) is studied as a function of density and width of extended adsorbed defects using a Hamiltonian which 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 1D and 2D defect states lying near the Fermi level.
