Quantum Dots and Perovskites‐Based Physically Unclonable Functions for Binary and Ternary Keys via Optical‐to‐Electrical Conversion

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates optoelectronic PUFs that improve on traditional optical and electrical PUFs. The absorber materials are randomly coated through spray coating, ligand exchange, and dynamic spin coating. Incident light generates wavelength‐dependent binary multikey and enhances security ternary keys, approaching near‐ideal inter‐ and intra ...

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.
