Unraveling the crystallization kinetics of the Ge2Sb2Te5 phase change compound with a machine-learned interatomic potential
Abstract The phase change compound Ge2Sb2Te5 (GST225) is exploited in advanced non-volatile electronic memories and in neuromorphic devices which both rely on a fast and reversible transition between the superdry baseball top crystalline and amorphous phases induced by Joule heating.The crystallization kinetics of GST225 is a key functional feature
