Direct ab-initio molecular dynamic study of ultrafast phase change in Ag-alloyed Ge${}_2$Sb${}_2$Te${}_5$

B. Prasai, G. Chen, D. A. Drabold

We employed ab-initio molecular dynamics to directly simulate the effects of Ag alloying ($\sim 5$ Ag concentration) on the phase change properties of Ge${}_2$Sb${}_2$Te${}_5$. The…
