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…
The impact of morphological structure and flexo-chemical strains on the electric transport mechanisms in the molybdenum-disulfide-oxide nanoflakes
Oleksandr S. Pylypchuk, Victor V. Vainberg, Vladimir N. Poroshin +11
Electric conduction mechanisms are studied in the pressed nanoflake powder of the molybdenum-disulfide-oxide (MoSxOy) depending on their content and structure. The MoSxOy nanoflake…
Reentrant polar phase induced by the ferro-ionic coupling in BiSmFeO nanoparticles
Anna N. Morozovska, Eugene A. Eliseev, Igor V. Fesych +9
Using the model of four sublattices, the Landau-Ginzburg-Devonshire-Kittel phenomenological approach and the Stephenson-Highland ionic adsorption model for the description of coupl…
Anomalous Behavior of the Dielectric and Pyroelectric Responses of Ferroelectric Fine-Grained Ceramics
Oleksandr S. Pylypchuk, Serhii E. Ivanchenko, Mykola Y. Yelisieiev +12
We revealed the anomalous temperature behavior of the giant dielectric permittivity and unusual frequency dependences of the pyroelectric response of the fine-grained ceramics prep…
Effective Dielectric Response of Dense Ferroelectric Nanocomposites
Oleksandr Pylypchuk, Serhii Ivanchenko, Yuriy Zagorodniy +4
We measured the temperature dependences of the capacity and dielectric losses of the tape-casted dense ferroelectric composites consisting of 28 vol.% BaTiO3 nanoparticles (average…
