Strategies are presented to identify phase change materials with fast transformation kinetics. A microscopic investigation of crystallization kinetics with a static tester and an atomic force microscope demonstrates that for different alloy compositions recrystallization proceeds either via growth from the crystalline rim or by nucleation and growth of critical nuclei. The influence of dielectric layers enables a further optimization of transformation kinetics.
