The use of pulsed electric acoustic technique for measuring electric field profiles in ferroelectric ceramic
(2002-12-01)
The pulsed electric acoustic technique, PEA, have been usually applied to probe space charge profiles in polymers. In this work we show preliminary results obtained with lead zirconate-titanate and niobium, PZTN, ferroelectric ...

Space-charge polarization by confined ion migration in microstructured solid dielectrics
(Pergamon-Elsevier Science Ltd, 2019-02)
A continuum formulation for the effective electrostatic response of microstructured solid dielectrics undergoing intrinsic and extrinsic polarization is presented. The extrinsic polarization is produced by space charges ...
Separation of dielectric and space charge polarizations in CaCu3Ti4O12/CaTiO3 composite polycrystalline systems
(American Institute of Physics (AIP), 2007-04-02)
The complex analysis of dielectric/capacitance is a very useful approach to separate different polarization contributions existing in polycrystalline ceramics. In this letter, the authors use this type of spectroscopic ...
VACUUM POLARIZATION EFFECTS ON QUASINORMAL MODES IN ELECTRICALLY CHARGED BLACK HOLE SPACE-TIMES
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
We investigate the influence of vacuum polarization of quantum massive fields on the scalar sector of quasinormal modes in spherically symmetric black holes. We consider the evolution of a massless scalar field on the ...

Investigation of Ferroelectricity and Piezoelectricity in Polar and Non-polar Polymers
(2022-06-01)
An overview is presented of experimental investigations during two decades at the Polymer Group Prof. Bernhard Gross in Sao Carlos, Brazil, on the properties of piezoelectric polymers. The paper is focused on innovations ...
