Liquid-matter relaxor ferroelectrics by design [PDF]

Nature Communications
Knowing that traditional relaxor ferroelectrics stem from crystalline materials, one may ask whether they stabilize the liquid-matter analogy. The perspective is challenging and may enable a generic design of fluidic and flexible relaxor ferroelectrics ...

Evolution of dielectric and ferroelectric relaxor states in Al3+-doped BaTiO3

AIP Advances, 2015
In ferroelectric BaTiO3, we report the evolution of the Dielectric Relaxor and Ferroelectric Relaxor states as a function of B-site doped Al3+ concentration. The relaxor states occur after the paraelectric-ferroelectric phase transition upon cooling. Two

Ferroelectric-to-relaxor crossover in Sb doped PLZT x/52/48 (2 ≤ x ≤ 16) piezoelectric ceramics

Journal of Asian Ceramic Societies, 2014
Dielectric behavior and diffuse phase transition have been investigated in Sb doped lead lanthanum zirconate titanate (PLZT) ceramics to understand the role of La and Sb in ferroelectric-to-relaxor crossover.

Superlattice Engineering in Relaxor Ferroelectric-based Capacitors for Ultra-Highly Efficient Recoverable Energy Storage Density [PDF]

Nature Communications
In this work, we show that superlattice engineering, through the combination of relaxor ferroelectric 0.5Ba(Zr0.2Ti0.8)O3−0.5(Ba0.7Ca0.3)TiO3 and paraelectric SrTiO3 layers, is a powerful approach to simultaneously optimize energy density and efficiency ...
