Thermodynamics of Ferroelectric and Optical Properties in KNbO3
Aiden Ross, Venkatraman Gopalan, Long-Qing Chen
Potassium niobate (KNbO3) is a prototypical perovskite ferroelectric with large electro-optic and nonlinear optical responses, high optical damage thresholds and a rich sequence of…
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…
Terahertz-field activation of polar skyrons
Huaiyu Wang, Vladimir Stoica, Cheng Dai +27
Unraveling collective modes arising from coupled degrees of freedom is crucial for understanding complex interactions in solids and developing new functionalities. Unique collectiv…
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…
A Thermodynamic Theory of Proximity Ferroelectricity
Eugene A. Eliseev, Anna N. Morozovska, Jon-Paul Maria +2
Proximity ferroelectricity has recently been reported as a new design paradigm for inducing ferroelectricity, where a non-ferroelectric polar material becomes a ferroelectric by in…
