Amorphous Ge-rich GeSbTe (GST) alloys show higher thermal stability with respect to the prototypical Ge 2 Sb 2 Te 5 compound which makes them suitable for embedded phase-change memories of interest for automotive applications. During crystallization, Ge-rich GST undergoes a phase separation into pure Ge and less Ge-rich GST compound. The details underlying this transformation are, however, largely unknown. To this end, we present a density functional theory study of some decomposition pathways of amorphous Ge-rich GST alloys.

Abstract
Amorphous Ge-rich GeSbTe (GST) alloys show higher thermal stability with respect to the prototypical Ge 2 Sb 2 Te 5 compound which makes them suitable for embedded phase-change memories of interest for automotive applications. During crystallization, Ge-rich GST undergoes a phase separation into pure Ge and less Ge-rich GST compound. The details underlying this transformation are, however, largely unknown. To this end, we present a density functional theory study of some decomposition pathways of amorphous Ge-rich GST alloys.
