3D Meta‐Atoms for High Confinement of Mid‐IR Radiation

open access: yesAdvanced Optical Materials, EarlyView.
Mid‐infrared, three‐dimensional circuit‐like resonators with extreme field confinement are experimentally demonstrated. Combining simulations, measurements, and analytical modelling, a physical interpretation and prediction of the resonant modes supported by the structure, including their resonant frequency and radiative and non‐radiative losses, is ...

Liquid Metal‐Exfoliated SnO2‐Based Mixed‐Dimensional Heterostructures for Visible‐to‐Near‐Infrared Photodetection

open access: yesAdvanced 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 ...

Tuning Charge‐Separated State Lifetimes in Perovskite Nanocrystal‐Perylenediimide Hybrids

open access: yesAdvanced Optical Materials, EarlyView.
Functional perylenediimides with varied spacer lengths surface engineer CsPbBr₃ perovskite nanocrystals, yielding hybrid materials with new properties. Time‐resolved techniques reveal photoinduced charge separation from perovskite nanocrystals to perylenediimides, with microsecond‐lived charge carriers. Spacer length modulates charge carrier lifetimes,
