Extension of the dielectric tunability range in ferroelectric materials by electric bias field antiparallel to polarization

Nava Setter, Dragan Damjanovic, Marko Budimir

While in the paralectric phase of ferroelectrics, and in centrosymmetric materials in general, the dielectric tunability is symmetrical for positive and negative electric bias fields, in noncentrosymmetric materials this is not the case. By using the therm ...

Piezoelectric anisotropy: Enhanced piezoelectric response along nonpolar directions in perovskite crystals

Nava Setter, Dragan Damjanovic, Matthew Davis, Marko Budimir

This paper discusses the mechanisms that can contribute to the enhanced longitudinal piezoelectric effect along nonpolar directions in perovskite crystals, such as BaTiO3, PbTiO3, KNbO3, Pb(Mg1/3Nb2/3)O-3-PbTiO3 and Pb(Zn1/2Nb2/3)O-3-PbTiO3. Piezoelectric ...

Piezoelectric anisotropy and free energy instability in classic perovskites

Marko Budimir

Several members of the perovskite family are investigated: the temperature dependence of dielectric, elastic, piezoelectric and coupling coefficients of KNbO3 in its orthorhombic ferroelectric phase is determined experimentally; the values of dielectric st ...

Enhancement of the piezoelectric response of tetragonal perovskite single crystals by uniaxial stress applied along the polar axis: A free-energy approach

Nava Setter, Dragan Damjanovic, Marko Budimir

The influence of the uniaxial bias stress on the piezoelectric properties of tetragonal BaTiO3 and PbTiO3 monodomain crystals is modeled in the framework of the phenomenological Landau-Ginzburg-Devonshire theory. It is shown that tensile and compressive st ...
