Ultrahigh Piezoelectric Strains in PbZr_1-xTi_xO₃ Single Crystals with Controlled Ti Content Close to the Tricritical Point.

ABSTRACT: Intensive investigations of PbZr_1-xTi_xO₃ (PZT) materials with the ABO₃ perovskite structure are connected with their extraordinary piezoelectric properties. Especially well known are PZT ceramics at the Morphotropic Phase Boundary (MPB), with x~0.48, whose applications are the most numerous among ferroelectrics. These piezoelectric properties are often obtained by doping with various ions at the B sites. Interestingly, we have found similar properties for undoped PZT single crystals with low Ti content, for which we have confirmed the existence of the tricritical point near x~0.06. For a PbZr_{0.95 ± 0.01}Ti_{0.05∓ 0.01}O₃ crystal, we describe the ultrahigh strain, dielectric, optical and piezoelectric proper
