Chiral Metasurfaces with Multidimensional Tunability for Optical Chiral States
Advanced Optical Materials, EarlyView.A novel bilayer perovskite chiral metasurface enables tunable transitions between BIC‐associated vortex centres and circularly polarized states via rotational symmetry control. Breaking rotational symmetry and applying in situ rotation to the upper layer allows precise, omnidirectional tuning of C points in momentum space. This evolution forms a Möbius‐

Control Over the Microstructure of Vapor‐Deposited CsPbBr3 Enhances Amplified Spontaneous Emission
Advanced Optical Materials, EarlyView.A photo‐physical and atomic‐resolution structural study of vapor‐deposited CsPbBr3 thin films is presented. The structure and performance of CsPbBr3 films is found to be highly sensitive to the precursor flux ratios during deposition. The optimal flux ratio has a small CsBr excess and produced films well‐suited for laser applications with excellent ...

State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide
Advanced Photonics Research, EarlyView.State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...

Advanced Sustainable Systems, EarlyView.CsFAPbI3 perovskite diodes show superior low‐voltage rectification. Ionic liquid incorporation suppresses ion migration and enhances voltage tolerance, enabling durable performance for AC–DC conversion and other optoelectronic devices. Abstract Metal halide perovskites have gained significant attention owing to their remarkable semiconductor properties
