Resolving glass transition in Te-based phase-change materials by modulated differential scanning calorimetry

, 2017
Glass transitions of Te-based phase-change materials (PCMs) were studied by modulated differential scanning calorimetry. It was found that both Ge2Sb2Te5 and GeTe are marginal glass formers with Delta T (= T-x - T-g) less than 2.1 degrees C when the ...
