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…
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…
Interfacial Effects and Negative Capacitance State in P(VDF-TrFE) Films with BaTiO3 Nanoparticles
Oleksii V. Bereznykov, Oleksandr S. Pylypchuk, Victor I. Styopkin +7
We analyze the temperature dependences of the effective dielectric permittivity of P(VDF-TrFE) films with BaTiO3 nanoparticles (with the average size 24 nm). Transition from a weak…
Ferroelectric Nanoparticles in Liquid Crystals: The Role of Ionic Transport at Small Concentrations of the Nanoparticles
Juliya M. Gudenko, Oleksandr S. Pylypchuk, Victor V. Vainberg +7
We reveal the visible influence of the ultra-small concentrations (1 wt.% or less) of the BaTiO3 nanoparticles (average size 24 nm) on the current-voltage characteristics and capac…
