Flexoelectricity in antiferroelectrics [PDF]
Applied Physics Letters, 2018 Flexoelectricity (coupling between polarization and strain gradients) is a property of all dielectric materials that has been theoretically known for decades, but only relatively recently it has begun to attract experimental attention. As a consequence, there are still entire families of materials whose flexoelectric performance is unknown. Such is the

Mimicking Antiferroelectrics with Ferroelectric Superlattices [PDF]
Advanced MaterialsAbstractAntiferroelectric oxides are promising materials for applications in high‐density energy storage, solid‐state cooling, and negative capacitance devices. However, the range of oxide antiferroelectrics available today is rather limited. In this work, it is demonstrated that antiferroelectric properties can be electrostatically engineered in ...
