Researchers at the University of Illinois at Urbana-Champaign have identified how twisted graphene sheets behave and their stability at different sizes and temperatures. The scientists performed computer simulations at different temperatures for different sizes of graphene sheets and then used insights from these simulations to develop an analytical model to predict the number of local stable states and the critical temperature required to reach each of these states.
