Ferroelectric modulated visual devices with spatial and temporal polarization‐sensitivity for information recognition and processing in visibility‐degraded environments

open access: yesInfoMat, EarlyView.
Conventional imaging systems often struggle to recognize objects accurately in challenging environments such as underwater or foggy scenes. We developed a polarization‐sensitive artificial vision device inspired by the mantis shrimp that uses advanced two‐dimensional materials and a ferroelectric layer to directly sense, process, and retain visual ...

Chiral Quasi‐BICs Stemming From a Γ‐point Degeneracy

open access: yesLaser &Photonics Reviews, EarlyView.
Band degeneracies universally exist in 2D periodic systems. However, the studies on the intrinsic properties of those isolated points remain limited. By exploring 3D chiral perturbations, chiral quasi‐BICs are achieved through a Γ‐point degeneracy in resonant metasurfaces with C4 symmetry.

Emergence of Rashba Spin‐Orbit Coupling in Staggered‐Gyromagnetic Photonic Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
Rashba spin‐orbit coupling emerges in a staggered‐gyromagnetic photonic crystal under a uniform out‐of‐plane magnetic bias. The staggered magnetization splits a four‐fold Dirac point into a Rashba band structure carrying helical spin textures, verified by a four‐band k‐p model.

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

open access: yesSmall, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...
