Abstract

We discuss specific structural properties of commercially used Te-based multicomponent phase-change alloys that make them materials of choice for memory applications. In particular, we suggest that presence of longer and shorter bonds between similar kinds of atoms in the crystalline state and the (shorter) bond lengths being significantly longer that the sum of covalent radii of the corresponding atoms are crucial for efficient switching between the crystalline and amorphous state.
