dc.description.abstract | We present a continuum model for spontaneous twisting of graphene nanoribbons driven by
compressive edge stresses. Based on a geometrically nonlinear theory of plates, we identify scaling
laws for the dependence of twist angles on ribbon width. Strikingly, we find the existence of a critical
width below which a ribbon will not undergo spontaneous twisting, preferring an in-plane stretching
mode instead. The model predictions are shown to be in excellent qualitative and quantitative
agreement with density-functional tight-binding simulations. More generally, our model provides a
unifying picture of twisting in graphene nanoribbons with different edge orientations and chemical
functionalizations that have been reported recently in the literature. | |
