Description
Summary:In natural and synthetic crystals, the pyroelectric effect is possible only in ten symmetry classes of crystals, but their technical capabilities are practically exhausted. Therefore, the quasi-pyroelectric effects obtained in the materials of other symmetries, which also have important applications in electronics, become relevant. These effects can be obtained in the layers of suitable materials by creating anisotropic mechanical conditions, as well as induced by an electric field applied to the paraelectrics and relaxor ferroelectrics. The work investigated physical mechanisms capable of causing a large thermoelectric response (similar to pyroelectricity) in the polar and non-polar structures. The analysis was carried out on the basis of Landau's thermodynamic theory and a number of simple models.
