Directly from glassy to crystal: Phase change material switches state without entering liquid phase

By Lisa McDonald / August 27, 2019

Phase change materials are an excellent way to store data—if you know how to effectively switch between the material’s glassy and crystal states. Researchers at the University of Arizona and RWTH Aachen University discovered unlike most glasses, the PCM Ge2Sb2Te5 can switch directly from glassy to crystal without entering the liquid phase.
