Bulk ferroelectric heterostructures

Interfaces in oxide heterostructures act as critical regions to induce emergent and novel types of functionality in thin films. Herein, we demonstrate the creation of bulk ferroelectric heterostructures (BFHs) in monolithic ferroelectrics by nanoscale elemental partitioning, unlocking functionalities beyond the reach o...

Tailoring the Electric Field Response of Porous BaTiO3 Ceramics Fabricated via a Sucrose-Assisted Process

Porous BaTiO3 (BTO) ceramics with controlled porosity were successfully fabricated using a simple and cost-effective sucrose-assisted processing route. Porosity was introduced by incorporating 10–50 vol% sucrose as a pore-forming agent, followed by sintering at 1350 °C for 2 h. The use of sucrose as an effective pore-f...

Engineering Local Polar Frustration in Lead‐Free Dielectric Ceramics for Ultrahigh Normalized Energy Storage Performance

Lead‐free dielectric capacitors require high‐recoverable energy density and thermal stability under low operating fields to prevent premature breakdown. Here, we demonstrate a design strategy for high‐performance lead‐free dielectrics based on two key principles: selecting a highly polarizable ferroelectric matrix...
