Abstract
Understanding crystallization kinetics is essential to select the high-performance materials for phase-change memory. By ultrafast differential scanning calorimetry, we found the distinct fragile-to-strong crossover crystallization kinetics in ZnSb and Zn28Sb54Te18 supercooled liquids. Zn28Sb54Te18 inherits the excellent thermal stability around glass transition from ZnSb and exhibits faster crystal growth rate close to melting temperature (Umax is 9.1 m s−1) and larger crossover magnitude f (2.3), compared to the typical fragile-to-strong crossover material Ag-In-Sb2Te. Such a material with a distinct fragile-to-strong crossover is helpful to improve their thermal stability nearby glass transition temperature and accelerate the phase transition speed close to melting temperature.
