Small, EarlyView.A novel dispersion‐phase defect‐healing strategy using Br‐doped PbS quantum dots (QDs) significantly stabilizes CsPbI3 perovskite (Pe) QDs by passivating internal vacancies. This approach reduces trap‐assisted nonradiative recombination, enabling high‐performance indoor photovoltaics with exceptional stability.

Integration of Refractive Microlenses on BP/MoS2 Photodiodes for Enhanced Infrared Photodetection
Small, EarlyView.This study demonstrates the successful integration of black phosphorus/molybdenum disulfide infrared photodetectors with refractive microlenses to significantly enhance detection. The design achieves a 20‐fold photocurrent enhancement, enabling a room‐temperature detectivity of 1.83 × 109 cmHz1/2W−1, and demonstrates high‐resolution (1023 × 768) single‐

Scalable Room‐Temperature Terahertz Graphene Cameras
Small Methods, EarlyView.ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Impact of Plasma Ashing on Mixed Monolayer Doping of Silicon
Small Methods, EarlyView.Mixed monolayer doping provides a controllable way to introduce phosphorus dopants into silicon. A gentle oxygen‐plasma treatment removes unwanted carbon while maintaining phosphorus on the surface. Following thermal diffusion, the treated silicon shows enhanced near‐surface n‐type behavior, demonstrating how carbon removal can tune molecular doping ...

Structural Concrete, EarlyView.Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...
