Glass forming tendency in ternary GexAs20Te80−x glasses examined using differential scanning calorimetry

The intermediate composition of GexAs20Te80−x glasses has been studied by differential scanning calorimetry. The intermediate glass formation and devitrification of Ge10As20Te70 is proved more stable than the vicinity of intermediate compositions because the activation energy of transition, Eg (122.5 kcal mol−1), of this composition shows a minimum at its average coordination number r = 2.4. The thermal stability of intermediate Ge10As20Te70 glass is discussed based on characteristic temperatures such as the glass transition temperature, Tg, the crystallization temperature, Tp, and the melting temperature, Tm. The crystallization results are analysed and both the activation energy of the crystallization process (Ec = 34.6 kcal mol−1 for the first peaks and Ec = 41.6 kcal mol−1 for the second peaks) and the crystallization mechanism is characterized (kinetic exponent n = 2.09 for the first peaks, and n = 1.02 for the second peaks). The phases at which the alloy crystallizes after the thermal process have been identified by x-ray diffraction. The diffractogram of the transformed material indicates the presence of microcrystallites of GeTe4 and AsTe, with an additional amorphous matrix remaining.
