HRTEM image and structural models of a G-twin boundary. (a), (b) HRTEM images taken along the common 〈[\bar 13\bar 1]〉 axis, showing a {211} twin boundary. The inset in (b) shows a hypothetical image obtained by mirroring a simulated HRTEM image with an offset value of 0.5. (c) The Fourier transform of the HRTEM image in (b). (d) A superposition of two simulated ED patterns (red and blue) in which the 211 reflections of both domains overlap with each other (black). (e) Skeletal graphs for the G-twin boundary in which the 3- and 5-connected vertices are highlighted with a yellow triangle and circles, respectively. (f) A 3D model of the G-twin boundary obtained by joining two 3D reconstructed copies, shown in (g), at {211} + 0.5.
