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 ...

Improved natural balancing with modified phase shifted PWM for single-leg five-level flying-capacitor converters [PDF]

, 2012
Flying capacitor converters (FCCs), as most multilevel converter topologies, require a balancing mechanism of the capacitor voltages. FCCs have the valuable property of natural voltage balancing when a special modulation technique is used.

Off‐Stoichiometry Engineering of the Electrical and Optical Properties of SrNbO3 Using Oxide Molecular Beam Epitaxy

Advanced Functional Materials, EarlyView.
The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...
