Intercalation‐Induced Phase Transitions in Ferroelectric α‐In2Se3

Advanced Science, EarlyView.
Using the electrolyte gating technique, the van der Waals ferroelectric semiconductor α‐In2Se3 undergoes a series of transitions from a ferroelectric semiconductor to a dirty metal and finally to a metal, accompanied by a structural transformation. Concurrently, the ferroelectric hysteresis window progressively narrows and eventually disappears with ...

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Composition-induced non-ergodic–ergodic transition and electrocaloric evolution in Pb(1−1.5x)La(x)Zr(0.8)Ti(0.2)O(3) relaxor ferroelectric ceramics

IET Nanodielectrics, 2019
Relaxor ferroelectrics, with polar nanoregions (PNRs), are good candidates for electrocaloric (EC) refrigeration. This study investigates the EC performance of the Pb(1−1.5x)La(x)Zr(0.8)Ti(0.2)O(3) relaxor ferroelectric ceramics by the direct measurement

Electric Field Modulation of Interlayer Coupling via Piezostrain in a Synthetic Antiferromagnet

Advanced Science, EarlyView.
Controlling the interlayer exchange coupling (IEC) in synthetic antiferromagnets (SAFs) using an electric field is a promising route toward energy‐efficient spintronic devices. In this study, electric field induced‐strain modulation of IEC in Co/Ru/Co SAF/PMN‐PT is demonstrated.

Free‐Volume Regulation Enables Significantly Enhanced Electrical Breakdown via Short‐Chain Molecular Spatial‐Positioning Intercalation into Poly(vinylidene fluoride)

Advanced Science, EarlyView.
An innovative molecular spatial‐positioning shimming strategy is developed to optimize the electrical properties of poly(vinylidene fluoride) (PVDF). By intercalating polyethylene wax (PE wax) short‐chain molecules into PVDF's free volume, the film achieves a significantly enhanced energy density of 32.67 J cm−3.

Atomic resolution microstructure study of Bi-doped SrTiO3

Journal of Advanced Dielectrics
Intrinsic SrTiO3 is a quantum paraelectric, but moderately Bi-doped SrTiO3 exhibits dielectric frequency dispersion similar to relaxor ferroelectrics. In this paper, detailed electron microscopic studies of the microstructures of Bi-doped SrTiO3 samples ...
