Simulated Nanoscale Peeling Process of Monolayer Graphene Sheet: Effect of Edge Structure and Lifting Position
Figure 1
(a) The schematic illustration of the model of the monolayer graphene sheet physically adsorbed onto the rigid graphite surface used in the simulation. The green-colored six-membered ring at the center position or left edge of the graphene sheet is assumed to be adsorbed onto the atomic force microscopy tip apex indicated by broken lines, and it is moved upward along the (or ) direction, by Å. Initial AB stacking registry of the red-colored graphene sheet with (b) armchair and (c) zigzag edge adsorbed onto the blue-colored graphite surface within the plane.
