Approaching the Glass Transition Temperature of GeTe by Crystallizing Ge<sub>15</sub>Te<sub>85</sub>
Abstract
<jats:sec><jats:label /><jats:p>Like many phase‐change materials, GeTe crystallizes upon heating at a conventional rate before the calorimetric glass transition is reached. This has so far prevented an unambiguous determination of its glass transition temperature <jats:italic>T</jats:italic><jats:sub>g</jats:sub>. Herein, a new approach is realized to estimate the glass transition temperature <jats:italic>T</jats:italic><jats:sub>g</jats:sub> for GeTe through progressive crystallization of Ge<jats:sub>15</jats:sub>Te<jats:sub>85</jats:sub>. Selective crystallization of pure tellurium during sub‐<jats:italic>T</jats:italic><jats:sub>g</jats:sub> annealing leads to a gradual change in the composition of the amorphous surrounding toward that of GeTe. This gives rise to a new endotherm whose onset temperature gradually approaches the <jats:italic>T</jats:italic><jats:sub>g</jats:sub> of GeTe.</jats:p></jats:sec>
