a Six nearest neighbors (yellow) and 12 second-nearest neighbors (blue) of a hexagon in a graphene lattice. b Representative events (red) in graphene growth or etching with their corresponding indexes (m, n) shown below each event. The blue atoms are those to be added or removed during the event of adding or removal. 1 and 2 are nucleation at zigzag edge during growth and etching, respectively; 3 and 4 are kink propagation at the ZZ and AC edges, respectively; 5 and 6 are armchair nucleation at an armchair edge during growth and etching, respectively; 7 and 8 are events at a convex corner; and 9 and 10 are events at a concave corner, respectively.
