Piezoelectric and pyroelectric Crystal Classes

Symmetry Pages

Piezoelectric ( C1 C2 Cs D2 C2v C4 S4 D4 C4v D2d C3 C3h D3 C3v C6 D6 D3h C6v T Td )
Pyroelectric ( C1 C2 Cs C2v C4 C4v C3 C3v C6 C6v )
The piezoelectric effect is the generation of an electric voltage upon application of mechanical stress. Pyroelectricity relates to the generation of an electrical voltage upon heating. The presence of these effects is dependent upon the crystal class and not upon the material, although the degree of the effect is material specific.
