Abstract

The melting behavior of a two-dimensional film consisting of N monolayers interacting with a flat substrate is studied by using the Lennard-Jones-Devonshire cell model. It is shown that for a freestanding film the transition is first order regardless of the number of layers, but the melting temperature decreases monotonically as a function of N. The introduction of a short range substrate potential has the tendency to smear out the melting transition. Quantitative results on the specific heat and entropy variations, as well as the fluctuation effects, are presented.
