Complete set of elastic, dielectric, and piezoelectric coefficents of 0.93Pb(Zn1∕3Nb2∕3)O3–0.07PbTiO3 single crystal poled along [011]

Abstract

The authors report a complete set of elastic, dielectric, and piezoelectric coefficients of rhomboheral phase 0.93Pb͑Zn 1/3 Nb 2/3 ͒O 3-0.07PbTiO 3 single crystal poled along ͓011͔ measured at room temperature. It was found that the electromechanical coupling coefficients k 32 and k 33 of this domain engineered single crystal can reach 0.86 and 0.87, respectively, and the piezoelectric coefficients d 32 and d 15 are −1460 and 1823 pC/ N, respectively. This complete set of data can meet the urgent need of device designers using these super piezoelectric crystals and also provide important information for fundamental studies on domain engineering.

Electromechanical characterization of Pb(In0.5Nb0.5)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 crystals as a function of crystallographic orientation and temperature

“…These modes are ͑001͒ / ͗100͘, ͑001͒ / ͗110͘, ͑110͒ / ͗001͘, and ͑110͒ / ͗−110͘, where the first number indicates the electrode face and the second number is the acoustic wave propagation direction. 5 It has been demonstrated that the highest transverse piezoelectric coefficients are obtained from crystals poled along ͗110͘ and vibrated along the ͗001͘ direction, [5][6][7][8][9][10] with small signal d 32 coefficients on the order of ϳ−1500 pC/ N and electromechanical coupling factor k 32 ϳ 0.90 in PZNT and PMNT crystals.…”

Temperature-Dependent Phase Transition in Orthorhombic [011]c Pb(Mg1/3Nb2/3) O3-0.35PbTiO3 Single Crystal

“…Recently, [011] c PMN-xPT relaxor ferroelectric single crystals, with compositions near the MPB, come into view due to their high transverse piezoelectric properties (d 31 > 2100 pC/N) [10][11][12][13][14]. Meanwhile, [011] c orthorhombic relaxor-PT crystal was reported with a high shear piezoelectric response of d 24 in single domain state, making it a promising candidate for novel sensor or transducer design [15].…”

Characteristic electrical properties of Pb(Sc1/2Nb1/2)O3–PbTiO3 ferroelectric crystals

“…Ferroelectric crystals such as Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT) and Pb(Zn 1/3 Nb 2/3 )O 3 -PbTiO 3 (PZN-PT) with morphotropic phase boundary (MPB) have been reported to exhibit excellent piezoelectric, electromechanical, and dielectric properties, which lead them to be promising candidates for high performance actuators and transducers [1][2][3][4][5][6]. However, their relatively low temperature of the maximum dielectric constant (T max ) and even lower depolarization temperature (T MPB ) greatly limit the applications in many fields, where the broad temperature range is desired.…”
