Query: Chlorine adsorption on the Cu(111) surface   We investigate the adsorption of chlorine on the Cu(111) surface with full
potential all-electron density functional calculations. Chlorine adsorption at
the fcc hollow sites is slightly preferred over that at the hcp hollow. The
adsorption geometry is in excellent agreement with electron diffraction and ion
scattering data. Adsorption energies and surface diffusion barriers are close
to those deduced from experiment.
