One of the least-known properties of solid materials, pyroelectricity is rigorously defined as
the temperature dependence of the spontaneous polarization in certain anisotropic solids. 1 …

The perovskite structure is one of the most wonderful to exist in nature. It obeys to a quite
simple chemical formula, ABX 3, in which A and B are metallic cations and X, an anion …

Both the pyroelectric and electrocaloric effects originate from the cross-coupling between
polarization and temperature in insulating dielectrics. Although both effects have been …

Ferroelectric material BaTiO 3 (BTO) with intrinsic spontaneous polarization demonstrates
excellent pyroelectric effect that output current/voltage signals can be observed even by …

Photoexcited pyroelectricity in ferroelectrics allows the direct conversion of light radiation
into electric signal without external power source, thus paving an avenue to promote …

Ferroelectricity enables key modern technologies from non-volatile memory to precision
