Recent research has shown that two-dimensional confined GeTe PCLs exhibit a distinct fragile-to-strong crossover behavior, with a crossover magnitude of 2. This confirms that two-dimensional confinement can induce FSC in PCLs, highlighting their fast crystallization and good thermal stability.
Recent fragile-to-strong crossover (FSC) concept in the crystallization kinetics study of phase-change supercooled liquids (PCLs) is attractive for screening the high-performance phase-change materials. It is important to search the FSC behavior in confined PCLs, like the two-dimensional confined PCLs, which is believed has fast crystallization and good thermal stability. Together with the ultrafast differential scanning calorimetry measurement and the generalized Mauro-Yue-Ellison-Gupta-Allan viscosity model, we here studied the crystallization kinetics of two-dimensional confined GeTe PCLs. It was found such confined PCLs has distinct FSC with large crossover magnitude is 2, confirming two-dimensional confinement can trigger the FSC behavior in PCLs. (C) 2020 Acta Materialia Inc.
