摘要：

Based on the ellipsometric observation of the phase change of stoichiometric Ge-Sb-Te at moderately elevated temperature, we find that the kinetics of crystallization of Ge-Sb-Te is described by the modified Johnson-Mehl-Avrami (JMA) equation, which implies that the first stage of cascaded crystallization of Ge-Sb-Te is a true nucleation-dominated process such that the formation of nuclei is stimulated by preexisting nuclei.
