Universal Properties of Ferroelectric Domains

open access: yesPhysical Review Letters, 2009
Basing on Ginzburg-Landau approach we generalize the Kittel theory and derive the interpolation formula for the temperature evolution of a multi-domain polarization profile P(x,z). We resolve the long-standing problem of the near-surface polarization behavior in ferroelectric domains and demonstrate the polarization vanishing instead of usually assumed

Morphology and Ferroelectric Properties of Semiconducting/Ferroelectric Polymer Bilayers [PDF]

open access: yesMacromolecules, 2019
Bilayers of the ferroelectric polymer poly(vinylidene fluoride-trifluoroethylene), P(VDF-TrFE) on semiconducting poly(3-hexyl thiophene) substrates have been prepared by sequential spin-coating. Here, we present a study of the polarization of this ferroelectric/semiconducting bilayer as a function of the semiconductor thickness by piezoresponse force ...

Anomalous Optical Properties of KTN:Li Ferroelectric Supercrystals

open access: yesNanomaterials, 2023
We report a spectroscopic investigation of potassium–lithium–tantalate–niobate (KTN:Li) across its room-temperature ferroelectric phase transition, when the sample manifests a supercrystal phase. Reflection and transmission results indicate an unexpected temperature-dependent enhancement of average index of refraction from 450 nm to 1100 nm, with no ...
