title: Electromechanical properties of orthorhombic 0.24Pb(In1/2Nb1/2)O3-0.43Pb(Mg1/3Nb2/3)O3-0.33PbTiO3single-domain crystal.
abstract: Single-domain structure with orthorhombic symmetry has been achieved in morphotropic phase boundary composition 0.24Pb(In1/2Nb1/2)O3-0.43Pb(Mg1/3Nb2/3)O3-0.33PbTiO3ternary single crystal by applying a large field along the pseudo-cubic direction [011]c. Complete set of elastic, piezoelectric, and dielectric constants has been determined with self-consistency. This crystal shows very large thickness shear piezoelectric coefficientd15=4324 pC/N and extremely high shear electromechanical coupling factork15=96%. Three-dimensional orientation dependence of the longitudinal piezoelectric constantd33was calculated and compared with experimental values, which revealed nearly 20% extrinsic contributions in domain engineered [001]cand [111]cpoled conditions.
