Figure 3. The total free energy as a function of number of layers and interfacial separation of Gr in (a) rectangular Gr with R = 2, 5, 10 nm and (b) circular Gr with W = 2, 5, 10 nm. The inset of (a) and (b) show the relationship between the critical interface separation and the membrane thickness under various R and W, respectively.
