Piezoelectric softening by Nb substitution in (Ba,Pb)ZrO

Nava Setter, Nicola Marzari, Dragan Damjanovic, Alberto Biancoli, David Bahati

Donor doping is commonly applied for softening of the piezoelectric and dielectric properties and facilitation of polarization switching in the ubiquitous Pb(Zr,Ti)O-3 [PZT] ceramics. The origin of the donor-dopant effects is not entirely clear. (Pb,Ba)ZrO ...

Nonlinear dynamics of polar regions in paraelectric phase of (Ba1-x,Srx)TiO3 ceramics

Dragan Damjanovic

The dynamic dielectric nonlinearity of barium strontium titanate (Ba1-x, Sr-x) TiO3 ceramics is investigated in their paraelectric phase. With the goal to contribute to the identification of the mechanisms that govern the dielectric nonlinearity in this fa ...

Comparison of apparent activation energies for densification of alumina powders by pulsed electric current sintering (spark plasma sintering) and conventional sintering-toward applications for transparent polycrystalline alumina

Paul Bowen, Michael Stuer, Zhe Zhao, Claude Paul Carry

In the quest for high real in-line transmittances for transparent polycrystalline alumina (PCA), we need defect free processing. One of the biggest advances in producing high density defect free ceramics over recent years has been the advent of spark plasm ...

Symmetry breaking in hexagonal and cubic polymorphs of BaTiO3

Dragan Damjanovic, Alberto Biancoli

BaTiO3 appears in cubic and hexagonal variants, both of which are centrosymmetric. Samples of cubic BaTiO3 are known to exhibit breaking of the centric symmetry locally and globally. It has been proposed that the local symmetry breaking originates in polar ...

Temperature Dependent Impedance Spectroscopy and Thermally Stimulated Depolarization Current (TSDC) Analysis of Disperse Red 1-co-Poly(methyl methacrylate) Copolymers

Frank Nüesch, Yee Song Ko

The dielectric relaxation processes of polymethyl methacrylates that have been functionalized with Disperse Red 1 (DR1) in the side chain (DR1-co-MMA) were studied with temperature dependent impedance spectroscopy and thermally stimulated depolarization cu ...

Short- and long-range polar order contributions to the Ferroelectric phase of Ca2+ doped SrTiO3

Alexander Tagantsev

Short- and long-range impurity-induced polar ordering in Sr1-xCaxTiO3 (x = 0.014) single crystals was investigated and discussed on the basis of light refraction, morphic birefringence and temperature-dependent dielectric hysteresis loop measurements. Anew ...

Internal electrical and strain fields influence on the electrical tunability of epitaxial Ba0.7Sr0.3TiO3 thin films

Nava Setter, Sarunas Bagdzevicius, Silviu Cosmin Sandu, Barbara Maraston Fraygola

Perpetual demand for higher transfer speed and ever increasing miniaturization of radio and microwave telecommunication devices demands new materials with high electrical tunability. We have investigated built in electrical and strain fields' influence on ...

Two-dimensional Frohlich interaction in transition-metal dichalcogenide monolayers: Theoretical modeling and first-principles calculations

Thibault Daniel Pierre Sohier

We perform ab initio calculations of the coupling between electrons and small-momentum polar-optical phonons in monolayer transition-metal dichalcogenides of the 2H type: MoS2, MoSe2, MoTe2, WS2, and WSe2. The polar-optical coupling with longitudinal optic ...

Highly stretchable dielectric elastomer composites containing high volume fractions of silver nanoparticles

Heinrich Hofmann, Jose Enrico Quijano Quinsaat

The dielectric permittivity (epsilon') of a polymeric material can be significantly increased when blended with conductive fillers at concentrations approaching the percolation threshold. However, reproducible synthesis of such composites is after decades ...
