Dielectric properties of K(Ta0,55Nb0,45)O-3 [KTN] single crystals with < 100 > and < 011 > crystallographic orientation were studied. Temperature dependencies of dielectric permittivity of monodomain and polydomain crystals of these orientations are compar ...
The dielectric response of ferroelectric-dielectric composites is theoretically addressed. Dielectric permittivity, tunability (relative change of the permittivity driven by dc electric field), and loss tangent are evaluated for various composite models. T ...
Dielectric and piezoelectric properties of K(Ta0.51Nb0.49)O3 [KTN] single crystals along [100], [001] and [011] pseudo-cubic crystallographic orientations are reported and discussed. Temperature dependencies of dielectric permittivity in tetragonal phase o ...
The dielectric properties of undoped, Nb-, and Fe-doped Pb(Zr,Ti)O3 ceramics with composition near morphotropic phase boundary were investigated in the frequency range from 1 MHz to 20.2 GHz at room temperature. Temperature dependences of dielectric permit ...
It was noticed long time ago that the dielectric permittivity of BaTiO3 single crystals in the rhombohedral phase varies from observation to observation, but the microstructure mechanism behind this phenomenon remained unclear. We show that the variations ...
The presence of free charges and numerous discontinuities separating liquid, gas, and solid phases in partially saturated soils give rise to Maxwell-Wagner polarization that may significantly affect bulk dielectric permittivity measurements. Evidence sugge ...
The paper describes processing and dielectric properties of 0.65Pb(Mn1/3Nb2/3)O-3-0.35PbTiO(3) films deposited on alumina and silicon substrates by screen-printing. Ink development and problems associated with adhesion of electrodes to substrate are discus ...
A phenomenological Landau-theory model, where a crystal on cooling from a state with polar symmetry exhibits a maximum of dielectric permittivity and polarization-field hysteresis loops, is offered. The model is equivalent to that of a true ferroelectric i ...
The dielectric response of a ferroelectric film with bilinear coupling between order parameter and strain is theoretically addressed. An exact solution for the total (lattice and domain contributions) dielectric permittivity of the system for the case wher ...
We study the electronic structure and the dielectric permittivity of ultrathin oxide layers on Si(I 00) substrates. By considering two different Si(l 00)-SiO2 interface models, we first show that the electronic structure in the interfacial oxide differs fr ...
