An ultrathin ferroelectric capacitor, designed by researchers from Japan, demonstrates strong electric polarization despite ...

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, ...

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 ...

Controlling magnetic states in materials typically requires continuous power or only works in rare, specialized systems. Researchers developed a general theory showing how electric fields can ...

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 ...
