Origin of the High Piezoelectric Response inPbZr1−xTixO

First-principles studies of lone-pair-induced distortions in epitaxial phases of perovskiteSnTiO3andPbTiO3

“…12, when performance, cost, ease of preparation and precursors availability are taken into account, PZT still remains the almost perfect all-around piezoelectric material. The exceptional piezoelectric properties of PZT, compared to only moderate piezoelectricity of PbTiO 3 , are attributed to the emergence of a morphotropic phase boundary (MPB) 3,[15][16][17][18] near the Zr:Ti = 52:48 and high mobility of FE domain walls, indicating that the existence of large PJTE-induced structural distortions is a necessary but not sufficient ingredient for attaining colossal property responses.…”

“…This corresponds to earlier investigations that have shown similar enhancement in the electrical properties at the MPB. 1 Some investigators have attributed this to the coexistence of the tetragonal and rhombohedral phases 15 or presence of an additional monoclinic Cm phase, 16 while others have shown the existence of nanopolar regions in the MPB region of PZT which could result in enhanced properties. 17,18 The reduction of domain wall energies and the resulting nanometer scale domains has been predicted by Jin et al, who applied the adaptive state theory of martensites to ferroelectrics.…”

Piezoelectric-nanowire-enabled power source for driving wireless microelectronics

“…Lead zirconate titanate, PbZr x Ti 1 − x O 3 (PZT), is probably the most important piezoelectric material for sensors and actuators, owing to its remarkable piezoelectric performance 12,13 . However, the fabrication of PZT thin films 14 and microfibres 15 usually requires high temperatures (~650 °C) to increase the crystallinity 16 , which leads not only to high cost and incompatibility with general fabrication processes but also makes it difficult to integrate with soft materials, even though a transfer technique has been demonstrated recently 17 .…”
