Simulated Nanoscale Peeling Process of Monolayer Graphene Sheet: Effect of Edge Structure and Lifting Position
Figure 17
(a) The model of the red-colored monolayer graphene sheet physically adsorbed onto the blue-colored rigid graphite surface within the plane. The green-colored six-membered ring at the center position is moved upward along the (or []) direction, by Å. Initial AB stacking registry of the red-colored graphene sheet with the blue-colored graphite surface is assumed. (b) The vertical force, , acting on the center six-membered ring, plotted as a function of the lifting displacement .
