Advanced Optical Materials, EarlyView.Two dimensional (2D) atomically thin materials hold significant promise for next‐generation photodetectors but are limited by low light absorption and scalability challenges. This study presents a high‐performance photodetector integrating liquid metal‐derived 2D SnO2 with CdTe, enabling efficient visible to near‐infrared detection and offering a ...

Advanced Optical Materials, EarlyView.An optimized fabrication approach for the nanostructuring of optical metasurfaces from van der Waals materials like hexagonal boron nitride is presented. The resonator geometries show enhanced geometric homogeneity, resulting in a significant increase in quality factors of symmetry‐protected bound states in the continuum resonances.

High‐Resolution On‐Chip Digitally Tunable Spectrometer Based on Double‐Cascaded Ring Resonators
Advanced Photonics Research, EarlyView.An integrated spectrometer is here presented, based on two cascaded ring resonators covered with a phase change material. The Vernier architecture is implemented allowing for a digital scan of wavelengths. Resolution smaller than 0.1 nm can be achieved, together with a footprint ≈0.03 mm2 and a bandwidth of the order of tens of nanometers.

Advanced Science, EarlyView.In this work, the oxygen vacancy formation is reported at the Au‐TiO2 interface in strong metal‐support interaction (SMSI) photocatalyst. The oxygen vacancies faciliate electron transfer and favor the adsorption of water and methanol at photocatalyst surface, thus enhancing the kinetic of photocatalytic hydrogen generation. The SMSI concept is extended

Advanced Science, EarlyView.Unraveling the underlying mechanisms at the origin of ultra‐low thermal conductivity in pristine crystals is of central relevance to designing new functional materials. Single crystals of the candidate functional material BaBiO3 show an anomalous glassy thermal conductivity, which reveals the role of strong anharmonicity and additional scattering ...
