Two-Dimensional Disorder in Black Phosphorus and Monochalcogenide Monolayers

Identifies a critical energy scale governing the onset of structural disorder in black phosphorus and monochalcogenide monolayers, dividing these 2D materials into two classes: those that melt directly, and those (GeS, GeSe, SnS, SnSe) that undergo an order-disorder phase transition near room temperature first. The transition is modelled with a planar Potts model and connected to the experimentally observed Cmcm phase in bulk SnSe.
