Figure 6. Temperature dependence of the experimental EXAFS spectra [χ(k)k²] and their Fourier transforms (FTs) for the Sb and Te K-edges in Sb₂Te₃ (A and B) and Bi L₃-edge and Te K-edge in Bi₂Te₃ (C and D). The FTs were calculated in the k-space range of 3.0-15.4 Å^-1, and only the FT modulus is shown for clarity.
