Strontium Bismuth Titanate is a very promising material for high temperature piezoelectric applications, its elevated ferroelectric phase transition (530°C), linear piezoelectric properties under low field and relatively low room temperature conductivity ( ...
Pyrochlore free 0.9Pb(Mg1/3Nb2/3)O-3-0.1PbTiO(3) thin films were prepared from alkoxide-based solution precursors. Preferential (111) crystallographic orientation was obtained on TiO2/Pt/TiO2/SiO2/Si substrates by spin coating. Dielectric, electrostrictive ...
Quasi-amorphous BaTiO3 thin films (see Figure) represent a polar ionic solid without spatial periodicity. Most probably, polarity of the quasi-amorphous BaTiO3 is associated with directional ordering of crystal motifs formed in the steep temperature gradie ...
Relaxor Pb(Sc1/2Nb1/2)O-3 (PSN) thin films without pyrochlore phase were processed from the modified alkoxide solution precursors. The preparation of single phase PSN thin films has a narrow processing window due to the appearance of an undesirable pyrochl ...
Relaxor Pb(Mg1/3Nb2/3)O3(PMN) and its solid solutions with ferroelectric PbTiO3 (PT) are of considerable interest from both the applications and the scientific point of view. In the past, many attempts were made to prepare and study the properties of these ...
Dielectric permittivity of PbMg1/3Nb2/3O3 (PMN) relaxor was investigated as a function of DC bias and AC driving field. In single crystals, DC and AC field effects exhibited very different behavior, including anisotropy and sign of the effect. It was shown ...
Pyrochlore free Pb(Mg1/3Nb2/3)O-3 (PMN) thin films were prepared from alkoxide-based solution precursors. The influence of different seeding layers and chemical solution on the microstructures is shown. Dielectric, electrostrictive, and piezoelectric prope ...
Piezoelectric response nonlinearity is approached using the Preisach description of hysteretic systems as collection of distributed bistable units. The Preisach model and its recent physical interpretation in terms of moving domain wall in a stochastically ...
Weak field piezoelectric coefficient and strain were investigated in ferroelectric SrBi2Ta2O9 (SET) thin films by means of optical interferometry. Though the maximum polarization and dielectric constant were small enough (7 mu C/cm(2) and 150, respectively ...
In this paper, the resistive and piezoresistive properties of a commercial resistive composition (Du Pont 2041), often used for strain-gauge applications, are examined on several dielectric compositions, which themselves are deposited onto various ceramic ...
