The kink density and its influence on the growth velocity in the kinetic BCSOS model are studied using an exact finite-size analysis based on the transition matrix method and a kinetic Monte Carlo simulation at equilibrium and during growth. The bcc(001) surface fluctuates in the model through...

The influence of interaction and lattice coordination number on the reactivity and structure of adsorbed particles on a surface has been analysed for a reaction of a monomer and a dimer that dissociates, both of which are adsorbed on a surface and react. For the case without interaction there is...

Higher order clustering coefficients C(x) are introduced for random networks. The coefficients express probabilities that the shortest distance between any two nearest neighbours of a certain vertex i equals x, when one neglects all paths crossing the node i. Using C(x) we found that in the...

Tracer and collective diffusion of repulsively interacting particles adsorbed on a bivariate trap surface are studied by means of Monte Carlo modelling. Adsorption isotherms are obtained via simulations in the grand-canonical ensemble. Simulations in the canonical ensemble are used to mimick...

We generate a porous structure by computer simulation in (2+1) dimension using a bidisperse ballistic deposition model. Particles of two different sizes are deposited randomly creating a porous bulk bounded by a highly irregular upper surface. The structure of the interface is connected to the...

In this work we study the problem of tax evasion on a fully-connected population. For this purpose, we consider that the agents may be in three different states, namely honest tax payers, tax evaders and undecided, that are individuals in an intermediate class among honests and evaders. Every...

Molecular dynamics simulations were performed for eight different metals to calculate their constant volume heat capacity and latent heat in both liquid and solid phases. The atomic interaction for the simulations is taken as modeled by the n-body semi-empirical Gupta potential. The per atom...

A CO+NO→CO2+12N2 surface reaction model is studied by means of Monte Carlo simulations. The surface is represented by triangular and square lattices and the diffusion of N and lateral interaction between reactant nearest-neighbor adatoms is considered. The influence of diffusion of N to...

Grand canonical Monte Carlo simulations have been performed in order to study adsorption thermodynamics of pairwise interacting particles on fractal surfaces. Diffusion-limited aggregates (DLA) have been used as a substrate where interacting particles are adsorbed. In order to obtain aggregates...

In the present paper, patterns of diffusion-limited aggregation (DLA) grown on nonuniform substrates are investigated by means of Monte Carlo simulations. We consider a nonuniform substrate as the largest percolation cluster of dropped particles with different structures and forms that occupy...
