HR Z-contrast images of QDs and their integrated intensity (compostition related) maps. The images were acquired along the [110] zone axis of samples (a) S-Sb and (d) S-SbN, and their respective maps of the R values (R i ) of (b,e) cations and (c,f) anions. Higher values (hot colors) can be attributed to atomic columns with heavier elements, In or Sb, respectively. (g) The regions used for intensity integration over each atomic column.
