Ferroelectricity at molecular level

Phase Transitions, 2004
The synthesis of ultrathin ferroelectric nanostructures by the Langmuir–Blodgett method and their properties are reviewed. It is shown that ferroelectricity exists in one monolayer of the ferroelectric P(VDF-TrFE) copolymer, i.e., at the molecular level. The specific characteristics of switching of ultrathin ferroelectric films are established.

Relaxor Ferroelectric Polymers: Insight into High Electrical Energy Storage Properties from a Molecular Perspective

Small Science, 2021
Relaxor ferroelectric polymers exhibit both high dielectric constants and low remnant polarization and thus deliver much higher energy densities and greater charge–discharge efficiencies than normal ferroelectrics for capacitive energy storage ...

UV laser induced ferroelectric domain inversion in lithium niobate single crystals [PDF]

, 2010
UV radiation in the spectral region beyond ~ 320 nm is strongly absorbed by lithium niobate single crystals. The strong absorption and the consequent localized heating of the crystal triggers physical processes which can affect the state of the material ...
