Relaxor behavior and morphotropic phase boundary in a simple model

, 2013
A simple model to reproduce strong enhancement of dielectric response near the morphotropic phase boundary (MPB) is proposed. This model consists of long-range dipole-dipole interaction and compositional chemical disorder incorporated by the variation in

Preparation and ferroelectric properties of (124)-oriented SrBi4Ti4O15 ferroelectric thin film on (110)-oriented LaNiO3 electrode

, 2011
A (124)-oriented SrBi4Ti4O15 (SBTi) ferroelectric thin film with high volume fraction of {\alpha}SBTi(124)=97% was obtained using a metal organic decomposition process on SiO2/Si substrate coated by (110)-oriented LaNiO3 (LNO) thin film.

Electroactive materials with tunable response based on block copolymer self-assembly

Nature Communications, 2019
Ferroelectric polymers are key building blocks for flexible electronic devices, but lack functionality and ability to tune their ferroelectric response. Here the authors show a method to introduce functionality in ferroelectric polymers while preserving ...

Polarity-dependent ferroelectric modulations in two-dimensional hybrid perovskite heterojunction transistors

Nature Communications
The non-volatile spontaneous ferroelectric polarization field serves as a cornerstone for applying ferroelectric materials in electronic devices, yet it is frequently mitigated by charge trapping at defect sites. Achieving an effective transition between

Piezoresponse force microscopy study on ferroelectric polarization of ferroelectric polymer thin films with various structural configurations

AIP Advances, 2015
Ferroelectric polymer-based memory devices have attracted much attention due to their potential in low-cost flexible memories. However, bad retention property of recorded logic states limited their applications. Though mechanisms of retention degradation

Vortex ferroelectric domains

Journal of Physics: Condensed Matter, 2008
We show experimental switching data on microscale capacitors of lead-zirconate-titanate (PZT), which reveal time-resolved domain behavior during switching on a 100-ns scale. For small circular capacitors, an unswitched domain remains in the center while complete switching is observed in square capacitors.

Ferroelectric polarization and magnetic structure at domain walls in a multiferroic film

Nature Communications
Domain walls affect significantly ferroelectric and magnetic properties of magnetoelectric multiferroics. The stereotype is that the ferroelectric polarization will reduce at the domain walls due to the incomplete shielding of depolarization field or the
