Anomalies in the Heat-Capacity Signatures of Submonolayer Adsorbates with Attractive Lateral Interactions,
Abstract
The analytic closed form of the heat capacity signatures previously derived for the McQuistan-Hock (MQH) model of a lattice gas is applied to various adsorbed systems for which the lateral interaction varies from a few meV to about 300 meV. It is shown that whenever the adsorption system can be described by a two-dimensional gas on which the substrate effects are less important than the adatom adatom interactions, the computed temperatures at which the heat capacity signatures display their maximum are in excellent agreement with the experimental measurements.
