High‐Power Single‐Quantum‐Well 376 nm Ultraviolet A Laser with Low‐Threshold Current Density

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 6, June 2026.
A 376 nm ultra‐violet A (UV‐A) laser diode is demonstrated using a GaN waveguide and single‐quantum‐well active region to reduce optical loss and structural strain while improving carrier distribution. The device achieves 2.36 W output power, 822.9 mW/A slope efficiency, and 5.89 kA/cm2 threshold current density, showing a promising route toward high ...

Atomically Thin Sn:GaN‐GaN Homojunction for High‐Sensitivity β‐Ray Detection

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Gallium nitride (GaN), a third‐generation wide‐bandgap semiconductor renowned for its superior radiation tolerance, holds promise for advanced β‐ray detection. Herein, a scalable liquid metal‐assisted in situ synthesis method is presented to fabricate Sn‐doped GaN homojunctions via gallium oxide printing followed by ammonolysis, enabling ...

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Tuning Y‐Mg Supports for Improved Ni‐Catalyzed NH3 Decomposition: Structural Modulation and Mechanistic Insights

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Catalytic NH3 decomposition has garnered substantial attention for hydrogen transformation and storage. Ni‐based catalysts continue to suffer from limited thermal stability and suboptimal low‐temperature activity, largely attributed to an incomplete understanding of the structure‐activity relationships and reaction mechanisms governing their ...
