摘要：

The remarkable melting behavior of partial and complete N2 monolayers deposited on graphite is examined using a Monte Carlo procedure in which various concentrations of vacancies are introduced. The calculated melting temperatures and specific heats are in agreement with experiment over the surface density range 0.2 less-than-or-equal-to rho less-than-or-equal-to 1, where the upper limit is the density of the observed square-root 3 x square-root 3 monolayer structure. Various physical quantities are calculated, and the nature of the transition is discussed.
