Charged Domain Walls in BaTiO3 Crystals Emerging from Superdomain Boundaries (Adv. Electron. Mater. 6/2023)

Abstract

Charged Domain Walls In article number 2300005, Petr S. Bednyakov and Jiří Hlinka observe transient domain structure with multiple superdomains containing bundles of ferroelastic subdomains during the paraelectric to the ferroelectric transformation in the crystal of barium titanate under the off-axis electric field. Operando optical microscopy reveals that after the retraction of the paraelectric phase, the superdomain boundaries convert into the desired charged domain wall species.
