Trapped Fluorine Enables Thermally Stable Broadband Photodetection in Graphene/Fluorinated Graphene Heterostructure

open access: yesAdvanced Materials Technologies, EarlyView.
Fluorinated graphene has opened new opportunities for real‐world applications; however, its working and thermal stability are key issues for practical use. This study successfully demonstrates the stability of a fluorinated graphene‐based photodetector, achieved through a graphene, fluorinated graphene heterostructure (Gr/F‐Gr HS).

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

open access: yesAdvanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype
