Theory of the elastic constants of graphite and graphene
WebIn this section we develop a general elasticity theory for graphene membranes, where large displacements are taken into account. In Section 13.2.1, we present a simple interatomic force field model for the potential energy of graphene sp 2 bonds. This potential energy is then used to obtain the elastic energy for the graphene seen as a continuous … WebOct 1, 2024 · The atomic structure of graphene can be observed directly by transmission electron microscopy (TEM) (Fig. 2 b) which is particularly useful for the evaluation of the … highest generation in laptop
