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 ...

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 ...

From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing ...
