(a) X-ray pair distribution function (PDF) plot of \({\text {Sn}}_{0.7}{\text {Ge}}_{0.3}{\text {Te}}\) measured at 290 K and is fitted using cubic \(Fm\bar{3}m\) model. (b) Cubic \(Fm\bar{3}m\) structure of \({\text {Sn}}_{0.7} {\text {Ge}}_{0.3}{\text {Te}}\) (c) Temperature dependent Goodness of fit (\(R_w\)%) value for the total structure (2.5–20 \(\AA\)) and local structure (2.5–3.5 \(\AA\)) of \({\text {Sn}}_{0.7}{\text {Ge}}_{0.3}{\text {Te}}\) fitted with \({Fm}\bar{3}m\) model.
