(a) HAADF raw image with intensity plot of the sample of PbBi2(Te1-ySey)4. (y = 0.5) Structure model is also presented; (b) experimental ABF-image (RL deconvoluted); and (c) simulated image of 100% inner ordered PbBi2(Te1-ySey)4 (y = 0.5); (d) HAADF-STEM; (e) EELS-Te mapping; and (f) EELS-Se mapping in the same area; (g) magnified HAADF image with intensity profile; (h) intensity is plotted along the blue, green, and red arrows.
