UNRAVELING THE CRYSTALLIZATION KINETICS OF THE GE2SB2TE5 PHASE CHANGE COMPOUND WITH A MACHINE-LEARNED INTERATOMIC POTENTIAL

Unraveling the crystallization kinetics of the Ge2Sb2Te5 phase change compound with a machine-learned interatomic potential

Abstract The phase change here 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 crystalline and amorphous phases induced by Joule heating.The crystallization kinetics of GST225 is a key functional feature for the operatio
