Abstract
The remarkable melting behavior of partial and complete 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≤ρ≤1, where the upper limit is the density of the observed √3 × √3 monolayer structure. Various physical quantities are calculated, and the nature of the transition is discussed.
