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

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 ...

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.
