Crystallization behavior and structure of amorphous Ge15Te85 and Ge20Te80 alloys
Source abstract
Abstract
Crystallization behavior of the amorphous Ge 15 Te 85 and Ge 20 Te 80 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 Ge 15 Te 85 and Ge 20 Te 80 glasses is considered. Atomic distribution in the investigated Ge-Te amorphous alloys is simulated by means of the Reverse Monte Carlo technique.
