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 ...

Hole Transfer Dynamics in Thin Films of Mixed‐Dimensional Quasi‐2D Perovskites

Advanced Functional Materials, EarlyView.
Charge transfer dynamics in quasi‐2D perovskite (PEA2MAn−1PbnI3n+1), grown with a distinct dimensionality gradient are investigated. Selective excitation of the n = 4 phase reveals efficient hole transfer to n = 2 and n = 3 within tens of picoseconds, while n = 1 acts as a hole‐blocking layer. These findings highlight the importance of minimizing n = 1

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 ...
