摘要：

The herringbone orientational transition of N2 molecules adsorbed on the graphite (001) surface has been studied by Monte Carlo simulation. Using the recently developed histogram method combined with an analysis of finite-size scaling and the fourth-order energy cumulant, our results strongly suggest a continuous transition in this model, contrary to the results of previous simulation studies and renormalization-group analysis. The critical exponents are determined to be those of the three-state Potts model, in good agreement with recent experimental results on systems that belong to the same universality class.
