Ultrafast Radiative Recombination Engineering in InGaN/GaN Quantum Wells through Temperature, Alloy Fraction and Layer's Width Tuning for Photonics

Advanced Theory and Simulations, EarlyView.
A side‐view schematic illustrating intra‐ and inter‐band optical recombination processes in quantum wells, highlighting applications that depend on carrier dynamics and recombination lifetimes, such as lasers, photodetectors, and solar cells. Abstract Radiative lifetime (RT) on the picosecond to femtosecond scale plays a key role in enabling ultrafast ...

Design, Simulation, and Fabrication of High‐Performance Metamaterial Absorber for EMI Mitigation and THz NDT/Imaging Applications: A Shape‐Preserved GHz‐to‐THz Transition Approach

Advanced Theory and Simulations, EarlyView.
A novel metamaterial absorber is designed, simulated, and validated for both 5G mmWave and THz applications, achieving >95.8% and 90% absorption, respectively. Its polarization‐insensitive, scalable design enables applications in THz NDT, imaging, and EMI shielding.

Isolation Techniques of Micro/Nano‐Scaled Species for Biomedical Applications

Advanced Science, EarlyView.
Separating micro/nano‐scale bioparticles from samples is essential for disease diagnosis, prevention, and monitoring. Therefore, a comprehensive overview of the latest advanced separation technologies is provided, and characteristics and limitations based on six key performance parameters, including purity, recovery rate, throughput, resolution, size ...
