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‐

Perforation Enhances Sound Insulation in Plate Lattice Metamaterials
Small, EarlyView.Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...
