A two-stage mechanism was proposed for the rotational surface disordering phase transition of a molecular crystal. The existence of new intermediate regime between a low-temperature ordered state and a high-temperature disordered phase was studied using Monte Carlo simulations. A partial disorder, strongest for a subset of frustrated surface molecules was found in the intermediate regime.

Abstract
A two-stage mechanism was proposed for the rotational surface disordering phase transition of a molecular crystal. The existence of new intermediate regime between a low-temperature ordered state and a high-temperature disordered phase was studied using Monte Carlo simulations. A partial disorder, strongest for a subset of frustrated surface molecules was found in the intermediate regime.| File | Dimensione | Formato | |
