Effect of defects and pre-adsorbates on adsorption probabilities: a Monte Carlo simulation point of view

The possible effect of defects and the influence of pre-adsorbates on the coverage dependence of adsorption probabilities will be discussed by the proposed Monte Carlo simulation scheme. In particular, the quenching of the adsorbate-assisted adsorption with increasing defect density—observed for CO/Cu(1 1 0)—and the scaling of the adsorption probability curves with increasing coverage of pre-adsorbates—observed for CO–O/Ir(1 1 0)—can qualitatively be reproduced.
