Wafer‐Scale Synthesis of Mithrene and its Application in UV Photodetectors

Advanced Functional Materials, EarlyView.
A controlled tarnishing step on the silver surface precedes the solid‐vapor‐phase chemical transformation into silver phenylselenolate thin films. The approach yields crystals exceeding 1 µm with improved in‐plane orientation. Integration on graphene phototransistors demonstrates high photoresponsivity, positioning mithrene as a promising material for ...

Self‐Trapped Hole Migration and Defect‐Mediated Thermal Quenching of Luminescence in α‐ and β‐Ga2O3

Advanced Functional Materials, EarlyView.
Temperature‐dependent photoluminescence and first‐principles calculations reveal self‐trapped hole migration as the microscopic origin of thermal quenching in α‐ and β‐Ga2O3. The low migration barrier in α‐Ga2O3 enables defect trapping and enhances blue luminescence, while the higher barrier in β‐Ga2O3 preserves ultraviolet emission at elevated ...

The Dynamics of Interfacial Trap States in High‐Detectivity Near‐Infrared Photomultiplication Organic Photodetectors

Advanced Functional Materials, EarlyView.
Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

A Smart Magnetically Actuated Flip‐Disc Programmable Metasurface with Ultralow Power Consumption for Real‐Time Channel Control

Advanced Functional Materials, EarlyView.
The study proposes a 1‐bit programmable metasurface based on flip‐disc display, named flip‐disc metasurface (FD‐MTS). This new design enables ultralow energy consumption while maintaining coding patterns. It also exhibits high scalability and multifunctional flexibility.
