Paper Title:
Influence of the Annealing on the Thermal Stability of Ge-Sb-Te Materials for Recording Devices
  Abstract

Phase change memory materials of Ge-Sb-Te system [(GeTe)m(Sb2Te3)n (m : n = 1:1; 1:2; 2:1)] were studied during thermal cycling by differential scanning calorimetry, and thermal properties were determined. Reproducible endothermic peak in the range of 390-415°C was revealed in Ge2Sb2Te5, GeSb2Te4, GeSb4Te7, which may possibly influence on the kinetics and endurance of data reading processes in phase-change memory devices. The nature of this endothermic peak is discussed. It was shown that additional annealing of synthesized Ge2Sb2Te5 increase stability of structure and thermal properties of the material.
