Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Concurrent Interface Passivation and Contact Work Function Tuning in Organic Self‐Aligned Gate Transistors and Complementary Circuits Using Phosphonic Acid Self‐Assembled Monolayers

Advanced Functional Materials, EarlyView.
Self‐aligned gate transistors are developed with a single‐step dielectric passivation and fine‐tuning of source/drain electrode work function using phosphonic acid self‐assembled monolayers (SAM). This transistor architecture minimizes overlap capacitances and access resistance.
