Using ultra-thin parylene films as an organic gate insulator in nanowire field-effect transistors

, 2018
We report the development of nanowire field-effect transistors featuring an ultra-thin parylene film as a polymer gate insulator. The room temperature, gas-phase deposition of parylene is an attractive alternative to oxide insulators prepared at high ...

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

Advanced 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).

Enhanced Self‐Phase Modulation in Silicon Nitride Waveguides Integrated With 2D MoS2 Films

Advanced Materials Technologies, EarlyView.
ABSTRACT On‐chip integration of 2D materials provides a promising route toward next‐generation integrated optical devices with performance beyond existing limits. Here, significantly enhanced spectral broadening induced by self‐phase modulation (SPM) is experimentally demonstrated in silicon nitride (Si3N4) waveguides integrated with 2D monolayer ...

Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

Advanced Science, EarlyView.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...
