The commensurate-incommensurate transition of Kr monolayers on graphite. II. Wall and wall crossing energies

For pt.I see ibid., vol.18, p.3919 (1985). The authors calculate wall and wall crossing energies numerically as a function of V G , the modulation of the substrate potential, at T=0. The wall energy is negative if V G <or=11K. The wall profile does not agree with that predicted by the analytic theory, because of anharmonicity in the Kr-Kr interaction. Wall crossing energies have function of V G as wall energies.
