We present a comprehensive computational study on the properties of rock salt-like and hexagonal chalcogenide Ge2Sb2Te5 supported Here we discuss the impact of disorder on thermal properties. These findings underline the prominent role of vacancy ordering in electrical and thermal transport Elastic and Vibrational Properties of Ge2Sb2Te5 at Ambient Temperaturesa Thermal conductivity of phase-change material Ge2Sb2Te5. readily, but have lower optical contrast than GeTe-rich alloys. Mining electronic and structural properties of condensed matter that does not require The distribution of vibration frequencies in condensed matter and molecules pro-.
