Adsorption Phenomena

ABSTRACTTwo different adsorption phenomena are studied using, in particular, Monte Carlo techniques: (i) Lattice gas models with competing interactions of ANNNI-type are shown to describe various uniaxial commensurate and incommensurate structures as observed in chemisorbed overlayers such as H on Fe(110) and O2 on Pd(110).(ii) At interfaces of multi-state models (Potts, spin-i Ising models) nonboundary states are adsorbed preferably; critical properties of this “wetting” phenomenon are investigated.

Repulsive Interactions

We propose a new class of driven lattice gas with repulsive nearest-neighbor interactions. Particles are allowed to jump to empty next-nearest-neighbor (nnn) sites in addition to the standard nearest-neighbor moves. In contrast to previous model with repulsive interactions, the external driving field (E) acts only along the nnn directions and does not destroy ground state sublattice ordering. Extensive Monte Carlo simulations in two dimensions for small E are consistent with a line of continuous transitions with Ising exponents. First-order transitions are also found for larger E.
