Paper Abstract

The crystallization process of two types of phase change materials (Ge2Sb2Te5 and AgInSbTe) has been studied by in-situ annealing experiments in the column of a transmission electron microscope. Under the same heating rate (7.5K/s), the Ge2Sb2Te5 material starts to nucleate at 170°C, while AgInSbTe starts to nucleate at 250°C. The measured nucleation rate of Ge2Sb2Te5 is 8.2×1014 cm-3s-1 larger than nucleation is dominant for both Ge2Sb2Te5 and AgInSbTe with ZnS-SiO2 as the dielectric layer in the thinned samples.
