Abstract

Crystals of (1-x) Pb(A1/3Nb2/3)O3-x PbTiO3 (A = Zn+, Mg2+) were grown by the flux technique. The dielectric and piezoelectric properties as a function of composition and crystal orientation have been evaluated. Both MPB and non-MPB crystals were found to possess high piezoelectric properties. Values of longitudinal electromechanical coupling coefficients (k33)>90%, dielectric constants ranging from 3000 to 5000 with low dielectric loss <1% were observed for rhombohedral crystals. Tetragonal crystals with increased PbTiO3 content exhibited large thickness coupling coefficients (kT) >63% with relatively low dielectric constant (approximately 1000). Ultrahigh values of piezoelectric coefficients (d33) >2000 pC/N were also measured for non-MPB crystals and confirmed by direct E-field strain measurements. These properties are briefly discussed in relation to device performance.
