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 ...

Flexoelectricity is a phenomenon in which a strain gradient in a material induces an electric polarization. It is a coupling between a mechanical strain gradient and an electric polarization in ...

Over the past few decades, electronics engineers have been trying to develop new neuromorphic hardware, systems that mirror ...

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, ...

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 ...

The effect: polarisation and electric field are pointing in the same direction. With positive d33, the sample expands, whereas the material is contracting when d33 is negative. Since 2011, it has been ...
