The structural and thermodynamic properties of 13-atom argon clusters adsorbed on a substrate are studied using Molecular Dynamics simulations. The cluster atoms interact among themselves via a Lennard Jones potential, whereas the cluster-substrate interaction is modeled by a continuous model for the adsorbent surface. Heating and cooling processes on the system show that the adsorbed clusters exhibit solid and liquid like phases as well as a coexistence region of both of them. The strength of the cluster-substrate interaction determines the mechanism of desorption in the region of high temperatures.
