Ferroelectric Domains and Evolution Dynamics in Twisted CuInP 2 S 6 Bilayers (Small Methods 1/2026)

Year: 2026

Type: article

Abstract: Inside Back Cover Using density functional theory and deep-learning molecular dynamics, in article number 2500683, Kou and co-workers show that polar domains emerge and can be manipulated in twisted bilayers of ferroelectric CuInP2S6. Their thermal stability and polarization lifetimes are sensitive to twist angle and temperature, and tunable by external electric fields and strain, offering a pathway to control local polarization through rotational manipulation.
