18. The "hcp region" of the moiré is where the C atoms reside close to directly atop either a surface layer Ir atom or an fcc threefold hollow. Accordingly, subsurface Ir atoms (colored red in Figs. 1 2) can be seen through C-atom hexagons in the hcp region. Similarly, third-layer Ir adatoms (colored green in Figs. 1 2) are seen through C-atom hexagons in the "fcc region" of the moiré, and surface Ir adatoms are visible through the C-atom hexagons in the "atop region." According to Ref., Ir islands on graphene/Ir(111) equilibrate in the hcp region of the moiré.
