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…
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…
Electrodynamics of ferroelectric films with negative capacitance
I. Luk'yanchuk, A. Sené, V. Vinokour
We construct a comprehensive theory of the electrodynamic response of ferroelectric ultra-thin films containing periodic domain textures (PDT) with 180° polarization-oriented domai…
Terahertz Electrodynamics of Domain Walls in Thin Ferroelectric Films
Igor Luk'yanchuk, Alexey Pakhomov, Anaïs Sené +2
We investigate oscillation dynamics of a periodic structure of the domain walls in nanometricaly thin substrate-deposited ferroelectric films and superlattices. We calc…
Polarization vortex domains induced by switching electric field in ferroelectric films with circular electrodes
Laurent Baudry, Anaïs Sené, Igor A. Luk'yanchuk +2
We describe ferroelectric thin films with circular electrodes and develop a thermodynamic theory that explains previously mysterious experiments. It is found to be especially usefu…
Field-induced vortices in weakly anisotropic ferroelectrics
Anais Sene, Laurent Baudry, Igor A. Luk'yanchuk +1
In the micro- and nanoscale ferroelectric samples, the formation and the growth of domains are the usual stages of the polarization switching mechanism. By assuming the weak polari…
