The Character of Melting for Simple Molecules Deposited on Graphite

摘要: The microscopic character of melting for quasi–two dimensional N2adlayers on graphite is examined surface densities 0.2 ≤ ρ 1, where the upper limit corresponds to a complete monolayer. A Monte Carlo method, with multiple histogram procedure, employed determine various thermodynamic quantities. Using calculated specific heats and selected order parameters, determined at densities, mechanism shown be vacancy mediated. somewhat unusual behavior temperature versus density entirely due concentration their topology. Because this by free energy, our analysis should general. Preliminary results Xe supports claim.
