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…
Correlations of Spectroscopic and Dielectric Properties of Hafnia-Zirconia Nanoparticles
Yuriy O. Zagorodniy, Eugene A. Eliseev, Petr Jiricek +11
In this work we analyze correlations of X-ray photoelectron and diffraction spectra, and dielectric properties of hafnia-zirconia nanoparticles (the chemical compositions Hf0.4Zr0.…
A colossal dielectric response of Bi1-xSmxFeO3 nanopowders
Vladyslav O. Kolupaiev, Olexander S. Pylypchuk, Vladimir N. Poroshin +6
The dielectric permittivity of the pressed powder samples of Bi1-xSmxFeO3, with Sm content "x" varying in the range 0 - 0.2, has been investigated in the temperature range from 20…
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…
Composition-Driven Phase Evolution in Sm-Doped BiFeO3 via Latent-Field Reconstruction of Atomically Resolved STEM Data
Newsha Javanmardi, Christopher T. Nelson, Anna N. Morozovska +3
Functionalities of ferroelectric materials are governed by the spatial organization and coupling of polarization, strain, lattice rotation, and structural order accessible via atom…
Bilinear Flexo-Antiferrodistortive Coupling in Ferroelastics: Polar Twins, Antiphase Boundaries and Fingerprints of Alterelectricity
Eugene A. Eliseev, Anna N. Morozovska, Akash Saha +1
Using the Landau-Ginsburg-Devonshire approach we show that the linear gradient-type coupling between the electric polarization vector and antiferrodistortive long-range order param…
