Electric Charge Transport and Dielectric Properties of the Barium Titanate Ceramics Obtained by Spark-Plasma Sintering with Different Carbon Content
Oleksandr S. Pylypchuk, Victor V. Vainberg, Denis O. Stetsenko +9
Barium titanate (BaTiO3) ceramics with a different content of carbon were synthesized by spark-plasma sintering (SPS) at the temperature of 1100 C in vacuum under pressure. The con…
Coexistence of Ferroelectric and Relaxor-like Phases in a Multiferroic Solid Solution (1-x)Pb(FeNb)O-xPbMnO
Anna N. Morozovska, Victor N. Pavlikov, Yuriy O. Zagorodniy +7
Experimental and theoretical studies of unusual polar, dielectric and magnetic properties of room temperature multiferroics, such as perovskites Pb(FeNb)O (PFN)…
Elimination of the acoustoelectric domain and increasing of the emission intensity by means of shunting the lateral current in the InGaAs/GaAs heterostructures
P. A. Belevskii, M. N. Vinoslavskii, O. S. Pylypchuk
There has been experimentally implemented a technique of neutralization of an acoustoelectric domain under the conditions of the lateral transport of charge carriers in strong elec…
Domain Morphology, Electrocaloric Response, and Negative Capacitance States of Ferroelectric Nanowires Array
Anna N. Morozovska, Oleksii V. Bereznykov, Maksym V. Strikha +4
We analyzed the domain morphology, electrocaloric response, and negative capacitance states in a one-dimensional array of uniformly oriented, radial symmetric ferroelectric nanowir…
Colossal dielectric response of HfxZr1-xO2 nanoparticles
Oleksandr S. Pylypchuk, Victor V. Vainberg, Vladimir N. Poroshin +10
We reveal a colossal dielectric response of small (5 - 10 nm) oxygen-deficient HfxZr1-xO2 nanoparticles (x = 1 - 0.4), prepared by the solid-state organonitrate synthesis. The effe…
Dynamics of charge states at the surface of a ferroelectric nanoparticle in a liquid crystal
Juliya M. Gudenko, Oleksandr S. Pylypchuk, Victor V. Vainberg +7
The liquid crystal with suspended ferroelectric nanoparticles is an interesting object for fundamental research of the long-range dipole-dipole interactions; as well as it is promi…
