Pyroelectric response and depolarization behavior of (1−x)Pb(Sc1/2Ta1/2)O3-(x)PbTiO3materials

The pyroelectric response of selected compositions from this solid solution system have been investigated. The nature of the temperature dependence of the pyroelectric coefficient for the compositions examined indicate the presence of a relatively broad, curved morphotropic phase boundary, [x = 0.3–0.45]. The high values of pyroelectric coefficient achievable, in particular for low x compositions [x = 0–0.1], suggest potential application of these materials as highly efficient and versatile field-stabilized devices.
