MOLECULAR-DYNAMICS SIMULATION OF SUBMONOLAYER KRYPTON FILMS ON GRAPHITE

Molecular dynamics simulations of submonolayer krypton films on graphite show a first order transition from a low temperature √3×√3 registered phase to a disordered one which is fluid and not localized in the graphite wells (not lattice-gas-like). This contrasts with simulations in the absence of a substrate ordering potential. There the transition is continuous. © 1980 American Institute of Physics.
