Example Sentences

Determining whether pyroelectricity comes from the surface, rather than from inside a crystal, is not trivial.

From Nature

This is interesting, because it implies that the pyroelectricity does not simply arise from thermal expansion of the piezoelectric surface5, but from a true phase transition confined to the surface.

From Nature

Therefore, the pyroelectricity seems to arise from an inherent surface distortion.
