Optical Control of Ferroelectric Imprint in BiFeO3

Advanced Functional Materials, EarlyView.
Above‐bandgap irradiation at room temperature enables on‐demand optical control of defect‐driven built‐in electric fields in BiFeO₃ thin films, fabricated via scalable, chemical spray pyrolysis. These fields, otherwise “frozen‐in,” can cause severe device degradation, including non‐switchable polarization, dead layers near interfaces, and polarization ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

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, EarlyView.
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 ...
