Figure 5: Total angular-limited three-body correlation (ALTBC) of Ge2Sb2Te5 at temperatures T = 852 K, 925 K, 1024 K, and 1250 K, obtained from the vdW-DF2 AIMD simulations.

Figure 5

At the lowest temperature considered, two well-defined peaks indicative of Peierls distortion are observed. At higher temperature, the distortion becomes less pronounced. In particular, at T = 1250 K, the two peaks start to merge.
