(a) HRTEM image of the modulated twin domain, and (b)–(d) the fast Fourier transforms of (b) upper left part, (c) lower right part, and (d) twin boundary of the image. The inset at the right bottom shows the simulated HRTEM image. The white parallelogrammical frame shows the projection of the supercell on (001) plane.
