A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities
Journal of Raman Spectroscopy, EarlyView.Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Small Methods, EarlyView.This work compares conventional wet development and asynchronously pulsed plasma development for Sn‐based inorganic resists under delay and AMC exposure. While wet development induces CD variation, scumming, and bridging, pulsed plasma enables selective removal of non‐exposed regions, mitigating contamination effects and achieving defect‐suppressed ...

Enhanced Performance of an AlGaN-Based Deep-Ultraviolet LED Having Graded Quantum Well Structure
IEEE Photonics Journal, 2019 AlGaN-based deep ultraviolet light-emitting diodes (DUV LEDs) suffer from severe quantum confined Stark effect (QCSE) due to the strong polarization field in the quantum wells (QWs) grown on c-plane substrates.

An elegant route to overcome fundamentally-limited light extraction in AlGaN deep-ultraviolet light-emitting diodes: Preferential outcoupling of strong in-plane emission [PDF]
, 2018 While there is an urgent need for semiconductor-based efficient deep ultraviolet (DUV) sources, the efficiency of AlGaN DUV light-emitting diodes (LEDs) remains very low because the extraction of DUV photons is significantly limited by intrinsic material

Aggregate, Volume 7, Issue 6, June 2026.The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.
