Ferroelectric crystals are a special class of materials that exhibit spontaneous electric polarization, which can be reversed by applying an external electric field. These crystals have a ...

Scientists have discovered that ordinary ice is a flexoelectric material, capable of generating electricity when bent or unevenly deformed. At very low temperatures, it can even become ferroelectric, ...

Adding zinc ions to lithium niobate crystals cuts the energy needed for polarization switching by 69%, enabling visible-light programming of memristors for brain-inspired computing.

Schematic illustrations of (a) head-to-head (H-H) and (b) tail-to-tail (T-T) domain walls, respectively. These domain walls carry opposite polarization bound charges at their cores. In this study, a ...

In a study published in Nano Letters, researchers demonstrated that light can change the electric polarization within the domains of a relaxor material in just trillionths of a second. Depiction of ...
