Atomic configuration models of (a) AA, (b) AB, and (c) AB′ bilayer stacking structures. Graphene clusters can be stacked on top of the A graphene layer in three different ways. (f–g) The schematic structure model in each stacking geometry and the expected signal intensity ratio at the centre; the first- and the second-neighbouring atoms in the reconstructed real space images.
