Abstract

In this work, we consider thermodynamic properties of p( 7 × 7 )R19° structure, which appears at the coverage of 8 = 4/7ML when T ≤ 220 K, with regarding the nearest- neighbor interactions among adsorbates. The structural study of Held et al. [1] shows that at this coverage, the CO molecules bind to on-top(onefold coordinated) and bridge(twofold coordinated) substrate sites with a relative population of 1:3 respectively (Fig 1) [2]. For this coverage, the nearest neighbor interactions are significant and thereby the particles distribution on these sites is not random [3]. Our goal is to include such interactions on the particles distribution.
