Bernoulli principle in ferroelectrics
Anna Razumnaya, Yuri Tikhonov, Dmitrii Naidenko +2
Ferroelectric materials, characterized by spontaneous electric polarization, exhibit remarkable parallels with fluid dynamics, where polarization flux behaves similarly to fluid fl…
Morphology of Polarization States in Strained Ferroelectric Films
Léo Boron, Anaïs Sené, Yuri Tikhonov +3
Ferroelectric thin films under epitaxial strain exhibit a variety of vortex-like topological polarization textures. To analyze them, we build on the Ginzburg-Landau-Devonshire fram…
Topological ferroelectric chirality
Igor Luk'yanchuk, Anna Razumnaya, Svitlana Kondovych +2
Chirality, an inherent property of most objects of the universe, is a dynamic research topic in material science, physics, chemistry, and biology. The fundamental appeal of this ex…
Topological polarization networking in uniaxial ferroelectrics
Y. Tikhonov, J. R. Maguire, C. J. McCluskey +8
Discovery of topological polarization textures has put ferroelectrics at the frontier of topological matter science. High-symmetry ferroelectric oxide materials allowing for freedo…
Vortex states in a PbTiO ferroelectric cylinder
Svitlana Kondovych, Maksim Pavlenko, Yurii Tikhonov +2
The past decade's discovery of topological excitations in nanoscale ferroelectrics has turned the prevailing view that the polar ground state in these materials is uniform. However…
The ferroelectric field-effect transistor with negative capacitance
I. Luk'yanchuk, A. Razumnaya, A. Sené +2
Integrating ferroelectric negative capacitance (NC) into the field-effect transistor (FET) promises to break fundamental limits of power dissipation known as Boltzmann tyranny. How…
Controllable skyrmion chirality in ferroelectrics
Yu. Tikhonov, S. Kondovych, J. Mangeri +9
Chirality, an intrinsic handedness, is one of the most intriguing fundamental phenomena in nature. Materials composed of chiral molecules find broad applications in areas ranging f…
Properties of the low-frequency phonon spectra of ferroelectric barium titanate-based heterostructures
E. D. Gor'kovaya, Yu. A. Tikhonov, V. I. Torgashev +7
Polarized Raman spectra of the epitaxial Ba0.5Sr0.5TiO3 film, bi-color BaTiO3/Ba0.5Sr0.5TiO3 superlattice, and tri-color BaTiO3/Ba0.5Sr0.5TiO3/SrTiO3 superlattice were studied in a…
Hopfions emerge in ferroelectrics
I. Luk'yanchuk, Y. Tikhonov, A. Razumnaya +1
Paradigmatic knotted solitons, Hopfions, that are characterized by topological Hopf invariant, are widely investigated in the diverse areas ranging from high energy physics, cosmol…
Ferroelectric multiple-valued logic units
I. Lukyanchuk, E. Zaitseva, V. Levashenko +5
Employing many-valued logic (MVL) data processing allows to dramatically increase the performance of computing circuits. Here we propose to employ ferroelectrics for the material i…
Harnessing ferroelectric domains for negative capacitance
I. Luk'yanchuk, Y. Tikhonov, A. Sene +2
The pressing quest for overcoming Boltzmann tyranny in low-power nanoscale electronics revived the thoughts of engineers of early 1930-s on the possibility of negative circuit cons…
