Figure 2. Schematic illustrations of lattice defects as well as mechanical deformations.
A. Stone-Wales with 2 pentagons (green) and 2 heptagons (orange). B. Vacancy with one pentagon (green) and larger empty region (orange). C. Line defect. D. Edge defect. E. Point deformation. F. Nanoparticle strain. G. Planar/un-deformed substrate (green) with 2D material coating (gray). H. Wrinkled with sinusoidal profile (small strain buckling). I. “Crinkled” with sawtooth-like profile (large strain/postbuckling).
