Abstract
The dynamics of a Stone-Wales defect in graphene has been investigated using the computer simulation of its time evolution at different temperatures. The previously predicted thermally activated transitions between two energy-degenerate sinelike configurations of these defects have been directly demonstrated. The temperature dependence of the characteristic time of these transitions has been determined. Based on the analysis of the hypersurface of the potential energy, the activation energy and frequency factor in the Arrhenius law have been obtained.
