Monolayer solid of ${\mathrm{N}}_2/\mathrm{A}\mathrm{g}\mathrm{}\left(111\right)\mathrm{}$

An incommensurate monolayer solid of ${\mathrm{N}}_2/\mathrm{A}\mathrm{g}\mathrm{}\left(111\right)\mathrm{}$ is modeled using extensive molecular-dynamics simulations. The conditions treated range from the low-temperature orientationally ordered solid to the melting of the solid. The properties are evaluated as a function of spreading pressure. Comparison is made to recent experimental data for ${\mathrm{N}}_2/\mathrm{A}\mathrm{g}\mathrm{}\left(111\right)\mathrm{}$ and to results for ${\mathrm{N}}_2$ adsorbed on graphite, Cu(110), and MgO(001).
