Ferroelectricity in Single‐Crystalline BaTiO3 Nanodisks on Silicon

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectricity is studied in 20 nm thick single crystalline BaTiO3 nanodisks when scaling their diameter from ≈ 400 down to 100 nm. For 100 nm diameter, the vertical polarization component adopts three distinct patterns, and the lateral one shows a rotational invariance in‐plane, suggesting a combination of center‐type and flux‐closure domains.

Stretching‐Orientation Reinforced Double Network Solvent‐Free Eutectic Gels for Ultrarobust, Flexible Human‐Machine Interaction Devices

open access: yesAdvanced Functional Materials, EarlyView.
This work develops an ultrarobust, flexible, and solvent‐free eutectic gel featuring stretch‐induced orientation. Overcoming hydrogel limitations, the gel achieves record toughness (133.86 MJ m−3) while integrating strain/temperature/capacitive sensing.

Gated PN Junction in Ambipolar MoS2 for Superior Self‐Powered Photodetection

open access: yesAdvanced Functional Materials, EarlyView.
A high‐quality gated pn junction based on ambipolar molybdenum disulfide (MoS2) is demonstrated by employing a partial‐gate structure and a Pt bottom contact that forms a semi‐van der Waals interface, facilitating efficient hole injection into the channel.

Mechanisms of Anode Interfacial Phenomena and Multi‐perspective Optimization in Aqueous Alkaline Zinc‐Air Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Zinc‐air batteries demonstrate great potential for sustainable energy storage but face major anode‐related challenges. This review provides a mechanism‐driven overview of zinc anode interfacial issues, e.g. dendrite formation, passivation, self‐corrosion, and hydrogen evolution; and explores advances in electrode, surface, and electrolyte engineering ...

Domain Nucleation and Growth in an Epitaxially Grown Wurtzite Ferroelectric

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric domain nucleation and growth in epitaxial wurtzite (Al, B, Sc)N films are visualized through in situ transmission electron microscopy. Domains initiate near the bottom electrode and propagate laterally with zigzag walls, while unswitched regions remain near the electrode interfaces.

Additive‐Driven Phase Control for Stable and Efficient CsPbI₃ Solar Cells Via Ambient Low‐Temperature Processing

open access: yesAdvanced Functional Materials, EarlyView.
CsPbI₃ perovskite solar cells face stability issues due to high annealing temperatures and moisture. Butylammonium acetate (BAAc) enables stable phase formation at 160°C in ambient laboratory conditions, enhancing efficiency and stability, achieving 18.6% PCE, and maintaining over 81% efficiency after 1,000 hours of maximum power point tracking under 1
