Shortwave Infrared Light Detection and Ranging Using Silver Telluride Quantum Dots

Advanced Materials, EarlyView.
Post‐synthesis surface engineering and doping control significantly improve the performance of Ag₂Te CQD photodiodes, achieving a low dark current of 450 nA cm−2 at −0.5 V, an LDR exceeding 150 dB, and a rapid response speed of ≈25 ns. A proof‐of‐concept LiDAR demonstration in the SWIR using a nanosecond diode laser, achieves decimetre‐level resolution

Controlled Formation of Skyrmion Bags

Advanced Materials, EarlyView.
This work demonstrates stabilization of complex magnetic skyrmion bags in ferromagnetic thin films through precisely engineered anisotropy defects using ion irradiation. The researchers achieve controlled field‐ and laser‐induced generation of skyrmionia, target skyrmions, and higher‐order skyrmion bags at room temperature. This reliable platform opens

Revealing Trapped Carrier Dynamics at Buried Interfaces in Perovskite Solar Cells via Infrared‐Modulated Action Spectroscopy with Surface Photovoltage Detection

Advanced Materials, EarlyView.
A new spectroscopy technique (i.e., pump‐push‐surface photovoltage) is introduced that monitors trapped carrier dynamics at the buried interfaces in perovskite solar cells (PeSCs) via combining optical trap activation by infrared light with surface photovoltage detection.

Precision Synthesis of a Single Chain Polymorph of a 2D Solid within Single‐Walled Carbon Nanotubes

Advanced Materials, EarlyView.
The precise synthesis of 1D materials has enabled the discovery of physical properties only accessible in length scales close to the atomic scale. Herein, it is demonstrated that encapsulation within single‐walled carbon nanotubes with matching diameters leads to a stoichiometric quasi‐1D van der Waals polymorph of a 2D pnictogen chalcogenide, Sb2Te3 ...

Unperceivable Designs of Wearable Electronics

Advanced Materials, EarlyView.
Unperceivable wearable technologies seamlessly integrate into everyone's daily life, for healthcare and Internet‐of‐Things applications. By remaining completely unnoticed both visually and tactilely, by the user and others, they ensure medical privacy and allow natural social interactions.

Unlocking Multimodal Nonlinear Microscopy for Deep‐Tissue Imaging under Continuous‐Wave Excitation with Tunable Upconverting Nanoparticles

Advanced Materials, EarlyView.
This study introduces a multimodal nonlinear microscopy approach using upconverting nanoparticles (UCNPs) under continuous‐wave excitation. The UCNPs exhibit high‐order nonlinear optical responses, enabling deep‐tissue 3D imaging, video‐rate wide‐field imaging, and depth‐selective photomodulation.
