Pyroelectric thermo-wave probing of BaZr0.2Ti0.8O3 ceramics
Nicholas V. Morozovsky, Yuriy O. Zagorodniy, Mykola Yelisieiev +10
BaxZr1-xTiO3 ceramics with 0.15 < x < 0.25, which have high dielectric permittivity, small leakage currents and low dissipation factor, are promising materials for tunable capacito…
Flexo-Strain Engineering of Phonons and Ferrons in Thin Films of Van der Waals Ferrielectrics
Anna N. Morozovska, Eugene A. Eliseev, Yujie Zhu +6
The influence of the flexoelectric coupling on the fluctuations of electric polarization and elastic strains can lead to the principal changes of the dispersion law of soft optical…
Flexocoupling-induced phonons and ferrons in van der Waals ferroelectrics
Anna N. Morozovska, Eugene. A. Eliseev, Oleksiy V. Bereznikov +7
The contribution of flexoelectric coupling to the long-range order parameter fluctuations in ferroics can be critically important to the ferron dispersion and related polar, pyroel…
Electron transport in quasi-ballistic FETs subjected to a magnetic field
Mykola Yelisieiev, Vyacheslav Kochelap
We report the study of quasi-ballistic electron transport in short FETs subjected to magnetic field. Spatial distributions of electron concentrations, velocities, Hall currents and…
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…
Theory of quasi-ballistic FET: steady-state regime and low-frequency noise
Mykola Yelisieiev, Vyacheslav Kochelap
We present the theoretical analysis of steady state regimes and low-frequency noises in quasi-ballistic FETs. The noise analysis is based on the Langevin approach, which accounts f…
The free path and the generation rate of a fast-moving electron interacting with a dielectric media
Mykola Yelisieiev
In the framework of macroscopic continuous medium approach, we studied the interaction between a fast-moving charged particle and dielectric or semiconducting media with low energy…
