Crystallization behavior of the amorphous Ge15Te85 and Ge20Te80 alloys under heat treatment has been studied by means of differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The structure of the amorphous germanium tellurides has been investigated with high-energy synchrotron radiation. Based on an analysis of DSC and XRD results, a plausible model of the structure of the Ge15Te85 and Ge20Te80 glasses is considered. Atomic distribution in the investigated Ge-Te amorphous alloys is simulated by means of the Reverse Monte Carlo technique.
