Enhanced Piezoelectric Properties of Piezoelectric Single Crystals by Domain Engineering
Various engineered domain configurations were induced into barium titanate (BaTiO3) single crystals, and their piezoelectric properties were investigated as a function of (1) the crystal structure, (2) the crystallographic orientation and (3) the domain size. As a result, the orthorhombic mm2 BaTiO3 crystals showed the highest piezoelectric properties among three kinds of BaTiO3 crystals such a...
متن کاملPiezoelectric properties of domain engineered barium titanate single crystals with different volume fractions of domain walls.
A piezoelectric domain wall model has been developed to analyze the effective piezoelectric properties of domain engineered BaTiO(3) (BT) single crystals with different volume fractions of 90 degrees domain walls. The model takes into account the nonuniform deformation in the domain wall region, which can create additional anisotropy to enhanced functional properties of multidomain single cryst...

gelten soll, so ist auch M' (T) ^ M (T) ; die Magnetisierung ist also monoton „mit dem Spektrum". Die in Abschnitt III durchgeführten Näherungen für die Eigenwerte kommen nun gerade einer solchen Ersetzung des wahren Spektrums durch ein approximiertes gleich und für diese Ersetzung gilt (61). Denn sowohl / V als auch eist überall größer als seine Schmiegungsparabel, durch die wir die X -Abhängi...
متن کاملElastic, piezoelectric, and dielectric properties of multidomain 0.67Pb„Mg1Õ3Nb2Õ3...O3 – 0.33PbTiO3 single crystals
The elastic, piezoelectric, and dielectric constants of 0.67Pb~Mg1/3Nb2/3!O3–0.33PbTiO3 domain engineered single crystal were determined experimentally by using ultrasonic and resonance methods. It was confirmed that the single crystal system has large electromechanical coupling coefficient k33 ~;94%! and piezoelectric constant d33 ~;2800 pC/N! if the poling is done along the @001# of pseudocub...
متن کاملOrientation and Temperature Dependence of Piezoelectric Properties for Sillenite-Type Bi12TiO20 and Bi12SiO20 Single Crystals
The full matrix of electro-elastic constants of sillenite-type crystals Bi12TiO20 (BTO) and Bi12SiO20 (BSO) were determined by the resonance method, with d14 and k14 being on the order of 40–48 pC/N and 31%–36%, respectively. In addition, double-rotated orientation dependence of d33 was investigated, with the maximum values of 25–28 pC/N being achieved in ZXtl45°/54°-cut samples. The electrical...
