Chalcogenide phase-change alloys are an important class of materials for applications in data storage. In this work, we investigate the structural properties of the amorphous phase of the phase-change material Sb2Te. We show that all the atoms in Sb2Te are in a defective octahedral environment, that the majority of primitive rings are five- and four-membered, and that the voids are small and amount to about 2 % of the total volume of the system.

Abstract
Chalcogenide phase-change alloys are an important class of materials for applications in data storage. In this work, we investigate the structural properties of the amorphous phase of the phase-change material Sb2Te. We show that all the atoms in Sb2Te are in a defective octahedral environment, that the majority of primitive rings are five- and four-membered, and that the voids are small and amount to about 2 % of the total volume of the system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
