(Nanowerk Spotlight) For decades, researchers have sought to understand and harness the pyroelectric effect in biological materials. Pyroelectricity refers to the phenomenon where heating or cooling a ...

All ferroelectric materials are pyroelectric, however, not all pyroelectric materials are ferroelectric. Below a transition temperature called the Curie temperature ferroelectric and pyroelectric ...

A crystal’s surface has been found to behave as a distinct material that has temperature-dependent electrical polarization — despite the rest of the crystal being non-polar. Conventional piezo- and ...
