Heterogeneous grain-scale response in ferroic polycrystals under electric field [PDF]

, 2016
Understanding coupling of ferroic properties over grain boundaries and within clusters of grains in polycrystalline materials is hindered due to a lack of direct experimental methods to probe the behaviour of individual grains in the bulk of a material ...

Realizing Ultrahigh Dielectric Constant With Ultrawide Temperature Stability in Dual‐Phase BNT‐BST Ceramics by SPS Sintering

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Ceramic capacitors are critical components in advanced electronic devices, primarily due to their multi‐functionalities in energy/information storage and conversion. However, poor temperature stability remains a long‐standing challenge for practical applications, especially at extremely high‐ or low‐temperature conditions (e.g., > 200°C or ...

Regulating the Interphase Strain in High‐Entropy Oxide Thin Films – An Approach to Attaining Giant Energy Storage Capability under Moderate Electric Fields

Advanced Functional Materials, Volume 35, Issue 41, October 8, 2025.
This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...
