Crystal thermoelectric
WebPyroelectricity (from the two Greek words pyr meaning fire, and electricity) is a property of certain crystals which are naturally electrically polarized and as a result contain large electric fields. Pyroelectricity can be described as the ability of certain materials to generate a temporary voltage when they are heated or cooled. The change in temperature modifies … WebMay 22, 2024 · Crystal structures are grouped into 32 classes called crystal point groups based on the symmetries they contain. Crystal structures in the 21 of the crystal point groups that do not have a center of symmetry can be piezoelectric. We can use a similar technique to determine if a crystalline material is or is not pyroelectric.
