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.
