Abstract

Read online

The crystallization of phase-change materials is relevant to their applications in memory and neuromorphic computing devices. Cheng et al. show that the β-relaxation in Ge15Sb85 can be controlled by thermal annealing, leading to the tunability in its crystallization kinetics by one order of magnitude.
