Grain boundary interpretation in the interface between lattice 1 and lattice 3. a) Typical STEM image in the interface between lattice 1 and lattice 3. The rectangular region is chosen in the interface and magnified image of the selected region is presented in (b), where a regular sequences of atomic rings of 57 is observed. The GB with the sequence of atomic rings of 57 corresponds to sigma (Σ) = 13. c) Schematic of the atomic model for structural units with atomic rings (57).
