Phonons of Phase‐Change Materials
physica status solidi (RRL) – Rapid Research Letters, 2022 Phase‐change materials (PCMs) undergo a reversible transition from a semiconducting to a metallic state, nicely termed “incipient metal.” This transition is driven by a Peierls distortion. A model of covalent bonding is developed in a tight‐binding scheme that accounts for the drastic evolution of some properties of PCMs, among which the Grüneisen ...

Vanishing‐Harmonicity and Phase‐Change Materials [PDF]
physica status solidi (RRL) – Rapid Research Letters, 2021 Phase‐change material (PCMs) store data using the contrast (electrical or optical) between two phases: a conductive crystalline phase and a weakly conductive amorphous phase. Most PCMs have a distorted octahedral structure. The contrast comes mainly from the electronic structure.
