Resumen:
The purpose of the present work was to study the effect of the
adsorbateadsorbate interaction energy for the glycine/Cu(110) system using a
Monte Carlo simulation in the grand canonical ensemble. The dependence of the
surface pattern structures upon the temperature and diffusion rate was studied.
For either reversible or irreversible adsorption, the results showed that it is
possible to obtain condensed phases with a large degree of correlation for high
diffusion rates and temperatures. Depending on the set of interaction energies for
nearest- and next-nearest-neighbour molecules, these patterns form either hetero- or
homo-chiral footprint domains.
The results obtained are qualitatively consistent with the experimental pattern
observed by other authors and allow an interpretation of the different proposed
theoretical models used to explain experimental data.
