Investigation of the dielectric relaxation processes in PbZr0.65Ti0.35O3-BaFe12O19 multiferroic ceramic composites
(Elsevier B.V., 2014-12-15)
The dielectric relaxation processes have been investigated in multiferroic ceramic composites based on the ferroelectric PbZr0.65Ti0.35O3 (PZT) and ferrimagnetic BaFe12O19 (BaM) systems. The frequency dispersion of the ...
Phase transition and dielectric properties of La-doped Pb(Zr, Ti)O-3 antiferroelectric ceramics
(Pergamon-Elsevier B.V. Ltd, 2009-08-01)
Lanthanum modified lead zirconate titanate (PLZT) ceramics with a Zr/Ti (90/10) ratio were investigated for a 7 and 8 at% lanthanum content by dielectric spectroscopy, the Sawyer-Tower polarization technique and x-ray ...

Admittance and dielectric spectroscopy of polycrystalline semiconductors
(Elsevier B.V., 2007-01-01)
This text discusses about advantageous, powerful and limitations of admittance and dielectric spectroscopy in the characterization of polycrystalline semiconductors. In the context of polycrystalline semiconductors or ...
Electro-mechanical actuation performance of SEBS/PU blends
(Elsevier Ltd, 2019)
Dielectric elastomers have been regarded as truly artificial muscles for their electro-mechanical (EM) actuation performance. However, they require large driving voltages to present adequate actuation strains. The main ...
Structural and dielectric properties of hot-pressed poly(vinylidene fluoride)-based composites
(SAGE Publications, 2018-05)
The characterization of ceramic/polymer composites was performed on zinc oxide/poly(vinylidene fluoride) – ZnO/PVDF and barium titanate/poly(vinylidene fluoride) composites with varying filler concentration in order to ...
Structural and dielectric properties of hot-pressed PVDF-based composites
(SAGE Publications, 2017-08-03)
The characterization of ceramic/polymer composites was performed on zinc oxide/ poly(vinylidene ﬂuoride) - ZnO/PVDF and barium titanate/poly(vinylidene ﬂuoride) - BT/PVDF composites with varying ﬁller concentration in ...
Surface dielectric functions of a free-electron gas
(American Physical Society, 2002-12)
We investigate the surface dielectric response of a free-electron gas to a projectile moving parallel to the surface. Three theoretical models are examined, viz., the specular reflection and the parallel dispersion models, ...
Effect of oxidizing and reducing atmospheres on Ba(Ti0.90 Zr0.10)O3:2V ceramics as characterized by piezoresponse force microscopy
The effect of annealing atmospheres (Atamb, N2 and O2) on the electrical properties of Ba(Ti0.90Zr0.10 )O3:2V (BZT10:2V) ceramics obtained by the mixed oxide method was investigated. X-ray photoelectron spectroscopy (XPS) ...
