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 ...

Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters ...

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 ...

A technical paper titled “Two-dimensional ferroelectricity in a single-element bismuth monolayer” was published by researchers at National University of Singapore, Zhejiang University, Tianjin ...

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, ...

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 ...

The word “piezo” derives from the Greek word piezein, meaning “to press tightly”. Piezoelectricity refers to a material’s ability to convert mechanical energy (pressing) into electric energy ...
