Figure 1. Domain wall configurations for kink interactions. (A) Domain wall configurations containing one or two kinks. The structural details of the atomic kinks, kink pairs and strain fields near the kinks are shown in (B and C). The strain maps in (A-C) are colour-coded by the atomic-level strain: ɛ_xx. Green dashed lines in (A) indicate the position of domain walls. Red solid lines in (A) indicate the atomic steps of the kink structures.
