Exploring Double NDR Modulation and UV‐NIR Photodetection in MoS2/Sb2Se3 Heterostructures
Advanced Optical Materials, EarlyView.In this study, a van der Waals Sb2Se3/MoS2 heterostructure exhibits dual negative differential resistance (NDR) peaks at room temperature. The first originates from band‐to‐band tunneling, while the second, triggered under laser illumination, is attributed to trap states and recombination dynamics.

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy
Advanced Optical Materials, EarlyView.Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Advanced Optical Materials, EarlyView.The compositional engineering of Sn‐halide perovskite with alkylammonium chloride, combined with graded heterojunction formation using fullerene, is shown to significantly enhance crystallinity and reduce trap densities. Consequently, the resulting photodetectors achieve a 63.4% external quantum efficiency and a specific detectivity of 1.38 × 1011 ...

Topological Valley Photonic Waveguides: Scattering Matrix Evaluation for Linear Computing
Advanced Photonics Research, EarlyView.This research is focused on the design of a 6‐port junction via valley photonic crystal waveguides to achieve equal power splitting of an incident signal towards three other ports. An in‐depth study is carried out to extract its corresponding scattering matrix.

Record Negative Photoconductivity in N‐Polar AlGaN/GaN Quantum‐Well Heterostructures
Advanced Photonics Research, EarlyView.The negative photoconductivity (NPC) effect is experimentally observed in the N‐polar AlGaN/GaN quantum‐well heterostructures after introduction of a GaN/AlN superlattice back barrier. The NPC phenomenon appears in the N‐polar AlGaN/GaN quantum‐well heterostructures under infrared light illumination at room temperature.

Advanced Photonics Research, EarlyView.This article proposes a symmetry‐protected bound states in the continuum mechanism based on borophene metamaterials, achieving dual‐band broadband coherent perfect absorption (CPA) in the near‐infrared spectrum. By dynamically modulating carrier concentration, the operational bandwidth of CPA can be significantly expanded, effectively overcoming the ...
