Figure 7. Temperature-dependent radial distribution functions (RDFs) g(r) calculated from the results of RMC/EA simulations for Sb₂Te₃ (A and B) and Bi₂Te₃ (C and D). Vertical lines show calculated average interatomic distances at 10 K (blue) and 300 K (red). The nearest atom pairs are indicated for clarity. The Te2-Te2 atom pairs from different layers are highlighted in red.
