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.

Numerical Study on Resistance Change Characteristics of Phase Change Materials
Advances in Materials Science and Engineering, 2021 Phase change materials are a type of emerging materials whose states will change under certain conditions, which then lead to changes in resistance. To study the characteristics of the phase change materials, a numerical simulation model of the resistive

Switching Casimir forces with Phase Change Materials [PDF]
, 2010 We demonstrate here a controllable variation in the Casimir force. Changes in the force of up to 20% at separations of ~100 nm between Au and AgInSbTe (AIST) surfaces were achieved upon crystallization of an amorphous sample of AIST.
