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 ...

Phase Transitions in Bi/Ca Modified AgNbO3 Ceramics with Excellent Energy Storage Density and Storage Intensity

Small, Volume 21, Issue 32, August 14, 2025.
The debated ±EU current peaks are readily distinguished from the ±E2 current peaks in modified AgNbO3 ceramics, which show a particularly high recoverable energy density of 4.4 J cm⁻3 and a superhigh energy storage intensity of 21.46 × 10⁻3 J kV⁻¹ cm⁻2 at a low field of 205 kV cm⁻¹.

Physical Properties of the K0.5Na0.5NbO3 Compound Doped With Li, La, and Ti in Concentration Lower Than 1.3 mol%

International Journal of Ceramic Engineering &Science, Volume 7, Issue 4, July 2025.
Doping of KNN with Li, La, and Ti at concentrations less than 1.3 mol%, reduces structural defects, increases density, and enlarges grain size. These changes enhance the remnant polarization and pyroelectric response. Thermal diffusivity decreases when doping's leads to higher concentrations of the secondary phase.

Bifunctional Design of Ferroelectric‐Order and Band‐Engineering in Cu:KTN Crystal for Extended Self‐Powered Photoelectric Response

Advanced Science, Volume 12, Issue 6, February 10, 2025.
This work proposes a bifunctional design strategy of ferroelectric‐order and electronic‐band to improve the photocurrent and extend the responsive range simultaneously. In a Cu‐doped KTa1−xNbxO3 perovskite crystal, a conductive channel is constructed by “head‐to‐head” ferroelectric domains, associated with the emergence of micrometer‐scale supercells ...
