Phonons of Phase‐Change Materials
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 ...
