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 ...

(Nanowerk Spotlight) In their pursuit of device miniaturization, researchers are exploring the untapped potential of two-dimensional materials. These atomically thin crystals, with their unique ...

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, ...

Most materials we use in everyday life expand when they are heated. Metals, plastics, and many other materials grow slightly ...

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 ...

A new class of semiconductors that can store information in electric fields could enable computers that run on less power, sensors with quantum precision, and the conversion of signals between ...
