Continuum Plate Theory and Atomistic Modeling to Find the Flexural Rigidity of a Graphene Sheet Interacting with a Substrate

Figure 9

Results for an optimization with 𝛼=.26 nN nm, 𝑙=6.8 nm, and 𝑇=0 nN/nm. In (a), 𝑑=0.31 nm. In (b), 𝑑=0.37 nm. Note that the atoms on the edges of the layer, whose positions are prescribed, are not plotted because the continuum model does not describe the deflection of these atoms.
