ABSTRACT
Graphene features unique electronic, thermal, and mechanical properties, and the flexibility and strong attraction between graphene layers promotes the formation of self-folded nanostructures. Here we study the self-folding of mono- and multilayer graphene sheets, utilizing a coarse-grained hierarchical multiscale model derived directly from atomistic simulation. Our model, developed by enforcing assertion of energy conservation, enables the simulation of graphene folding across a range of length scales from nanometers to micrometers. Through theoretical and simulation analysis we show that the critical self-folded length is [formula], where C and γ are the bending stiffness per unit length and the surface energy per unit length.

    An opposite edge strip ops with respect to a given edge of a graph is the smallest subset of edges closed under taking opposite edges on faces. The Omega polynomial is a counting polynomial whose k-th coefficient is the number m(G,k) of ops containing k-edges. In this paper an exact formula for...

    Using first principles calculations, we investigate the electronic and magnetic properties of BNC biribbons, a laterally-heterostructured nanoribbon constructed by joining a graphene nanoribbon (GNR) and a BN nanoribbon (BNNR) with zigzag edges. We find that the spin-polarization and electronic...
