Strong coupling between coherent ferrons and cavity acoustic phonons
Yujie Zhu, Jiaxuan Wu, Anna N. Morozovska +7
Coherent ferrons, the quanta of polarization waves, can potentially be hybridized with many other quasiparticles for achieving novel control modalities in quantum communication, co…
The Influence of Electric Field on the Anisotropic Dispersion of the Flexocoupling Induced Phonons and Ferrons in Van der Waals Ferrielectrics
Anna N. Morozovska, Eugene A. Eliseev, Yujie Zhu +4
As has been shown recently, the influence of the flexoelectric coupling (shortly "flexocoupling") on the fluctuations of electric polarization and elastic strains can lead to the p…
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…
Pressure-induced toroidal order in molecular SnPS ferroelectrics
Konstantin Z. Rushchanskii, Mykola Medulych, Vitalii Liubachko +1
For the SnPS crystalline compound with a rich temperature--pressure phase diagram that contains the ferroelectric phase, semiconductor-to-metal transition, and supercon…
Ferri-ionic Coupling in CuInPS Nanoflakes: Polarization States and Controllable Negative Capacitance
Anna N. Morozovska, Sergei V. Kalinin, Eugene. A. Eliseev +3
We consider nanoflakes of van der Waals ferrielectric CuInPS covered by an ionic surface charge and reveal the appearance of polar states with relatively high polarization…
Size Effect of Negative Capacitance State and Subthreshold Swing in Van der Waals Ferrielectric Field-Effect Transistors
Anna N. Morozovska, Eugene A. Eliseev, Yulian M. Vysochanskii +2
Analytical calculations corroborated by the finite element modelling show that thin films of Van der Waals ferrielectrics covered by a 2D-semiconductor are promising candidates for…
