Title: Atomic displacements in pyroelectric and piezoelectric crystals
Abstract: Atomic displacements produced in pyroelectric crystals by a temperature change of one degree, or in piezoelectric crystals by the application of a stress of 106 Nm−2, are estimated in both cases to be on the order of 10−4 Å. Corresponding polarization changes caused by dipole rotations are estimated to be on the order of minutes of arc. A group of 12 pyroelectric and 10 piezoelectric crystals are considered in which known absolute senses of pyroelectric or piezoelectric coefficients lead to a derivation of the sense of the ionic displacements.
