Wireless, 3D Optical Sensor Fabricated Using Mechanical Buckling for Navigation and Agriculture Applications

Advanced Materials Technologies, EarlyView.
This study develops a 3D optical sensor formed by mechanical buckling and equipped with wireless communication for navigation. Off‐the‐shelf electronic components are assembled onto a flexible circuit board, followed by mechanical strain‐guiding, facilitating the integration of an out‐of‐plane sensing configuration with a signal processing module.

Unveiling Ultrafast Spin‐Valley Dynamics and Phonon‐Mediated Charge Transfer in MoSe2/WSe2 Heterostructures

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study reveals the potential to manipulate spin‐valley polarization dynamics in MoSe2/WSe2 heterostructures by quantifying different scattering processes following selective photoexcitation. The results show that these heterostructures enable ultrafast valley‐selective charge transfer, with phonon scattering playing a significant role in the ...

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

Advanced 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 ...

Quantum Emitters in Rhombohedral Boron Nitride

Advanced Optical Materials, EarlyView.
Rhombohedral boron nitride (rBN) is an emerging wide‐bandgap van der Waals (vdW) material with strong second‐order nonlinear optical properties. In this work, optically‐addressable spin defects and single‐photon emitters (SPEs) are fabricated deterministically in rBN.
