O Radical‐Induced n‐to‐p Transition in PbS Quantum Dots Enabling Enhanced and Stable Photogating in QD/IGZO SWIR Phototransistors

open access: yesAdvanced Materials Technologies, Volume 11, Issue 20, 21 October 2026.
An O radical‐induced n‐to‐p transition in PbS quantum dots (QDs) is achieved via atmospheric Ar/O2 treatment, enabling favorable band alignment and stable photogating in PbS QD/IGZO phototransistors. Interfacial defect passivation and Fermi‐level modulation, confirmed by XPS and UPS analyses, effectively suppress dark current, induce a positive VTH ...

Chalcogen Alloy‐Engineered Te2Se/Si Heterojunctions for Low‐Noise Complementary Metal‐Oxide Semiconductor‐Compatible Short‐Wave Infrared Imaging

open access: yesAdvanced Optical Materials, Volume 14, Issue 38, 16 October 2026.
A Te2Se/Si heterojunction designed through atomistic simulations reduces oxide‐related traps, dark current, and noise compared with pure tellurium devices. This CMOS‐compatible platform enables short‐wave infrared detection and high‐contrast imaging in a 14 × 14 array, highlighting a scalable strategy for robust, low‐noise SWIR photodetectors and image

Engineering Ultrastable Intrinsic Radicals: Graphene Quantum Dots With NIR‐II Emission for Dynamic Deep‐Tissue Bioimaging

open access: yesAdvanced Science, Volume 13, Issue 60, 28 October 2026.
Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

Drone-Acquired Short-Wave Infrared (SWIR) Imagery in Landscape Archaeology: An Experimental Approach

open access: yesRemote Sensing
Many rocks, minerals, and soil types reflect short-wave infrared (SWIR) imagery (900–2500 nm) in distinct ways, and geologists have long relied on this property to aid in the mapping of differing surface lithologies.
