Direct visualization of antiferroelectric switching dynamics via electrocaloric imaging
Pablo Vales-Castro, Miquel Vellvehi, Xavier Perpiñà +8
The large electrocaloric coupling in PbZrO3 allows using high-speed infrared imaging to visualize antiferroelectric switching dynamics via the associated temperature change. We fin…

Flexoelectricity in antiferroelectric ceramics
P. Vales-Castro, Krystian Roleder, Lei Zhao +3
Flexoelectricity (coupling between polarization and strain gradients) is a property of all dielectric materials that has been theoretically known for decades, but it is only relati…
