Abstract

By ab initio molecular dynamics simulations, we unraveled the unique network structure of amorphous Ge₁Sb₂Te₄, which shows high rank of ordering and mostly consists of distorted defective octahedrons with a small portion of distorted tetrahedrons. The phase transition from amorphous to cubic Ge₁Sb₂Te₄ would be mainly a process of angle rearrangements of tetrahedrons to octahedrons and vice versa.
