Vanishing‐Harmonicity and Phase‐Change Materials [PDF]

open access: yesphysica 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.

Switching Casimir forces with Phase Change Materials [PDF]

open access: yes, 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.
