摘要: For detailed applications of lattice-gas models to surface systems, multisite interactions often play at least as significant a role between pairs adatoms that are separated by few lattice spacings. We recall trio (3-adatom, non-pairwise) do not inevitably create phase boundary asymmetries about half coverage. discuss sophisticated application an experimental system and describe refinements in extracting energies from calculations total several different ordered overlayers. how lateral relaxations complicate matters when there is direct interaction the adatoms, issue important examining angular dependence step line tensions. connector model alternative viewpoint close with brief account recent work on organic molecule
