Next Generation of Thermal Barrier Coatings with High Temperature Metal‐Silicide Metamaterials
Advanced Optical Materials, EarlyView.Thermal metamaterials have emerged as a powerful platform in the engineering of radiative heat transfer across a broad range of applications, including thermal imaging, passive cooling, and thermo‐photovoltaics. Here, a novel application is presented for metamaterials: thermal dual barrier coatings (TDBCs).

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 Photonics Research, EarlyView.Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Observation of Localized Resonant Phonon Polaritons in Biaxial α‐MoO3 Nanoparticles
Advanced Science, EarlyView.Biaxial α‐MoO3 nanoparticles exhibit tunable, high‐Q mid‐infrared resonances driven by localized phonon polaritons. Combining a novel synthesis method, hyperspectral near‐field imaging and a unified theoretical analysis, this work reveals eigenmodes and resonance conditions in biaxial particles.

Advanced Science, EarlyView.Geometrically confined quasi‐van der Waals (qvdW) recrystallization of patterned gold induces localized tensile strain in monolayer MoS2, enhancing its optoelectronic performance. The strain, induced during annealing after hBN encapsulation, leads to a 65‐fold increase in photoluminescence and a two‐order magnitude boost in mobility, offering a ...
