a A distribution of SCS in Fig. 1a. The colored squares on each atomic column are according to the SCS color scheme in Fig. 2b. b A histogram of SCS in Fig. 1a, fitted with 5 Gaussians. The inset shows a depiction of the interface region. Ga atomic columns are in dark blue, As—in lighter blue, and columns containing Bi are in orange. c Simulated HAADF image of the GaAsBi structure shown in Fig. 2d. The number of Bi atoms in a column is shown in parentheses in orange to the right of each group-V column. The fitted SCS values are shown to the left of each column and are normalized to the largest SCS value in the supercell. d The model GaAsBi <110> structure rotated sideways to highlight Bi positions (orange), light blue-As, dark blue-Ga atoms. The arrow shows the incident beam direction
