Exfoliated Graphitic Carbon Nitride Nanosheets as Efficient Catalysts for Hydrogen Evolution Under Visible Light
Shubin Yang,Yongji Gong,Jinshui Zhang,Liang Zhan,Lulu Ma,Zheyu Fang,Robert Vajtai,Xinchen Wang,Pulickel M. Ajayan +8 more
TL;DR: Graphitic carbon nitride nanosheets are extracted via simple liquid-phase exfoliation of a layered bulk material, g-C3N4, to exhibit excellent photocatalytic activity for hydrogen evolution under visible light.
Journal ArticleDOI
Gated tunability and hybridization of localized plasmons in nanostructured graphene.
Zheyu Fang,Sukosin Thongrattanasiri,Andrea E. Schlather,Zheng Liu,Lulu Ma,Yumin Wang,Pulickel M. Ajayan,Peter Nordlander,Naomi J. Halas,F. Javier García de Abajo +9 more
TL;DR: Electrical tunability and hybridization of plasmons in graphene nanodisks and nanorings down to 3.7 μm light wavelength are demonstrated, showing evidence of an unexpected increase in plasmon lifetime with growing energy.
Journal ArticleDOI
Graphene-antenna sandwich photodetector.
TL;DR: Nanoscale antennas sandwiched between two graphene monolayers yield a photodetector that efficiently converts visible and near-infrared photons into electrons with an 800% enhancement of the photocurrent relative to the antennaless graphene device.
Journal ArticleDOI
Active Tunable Absorption Enhancement with Graphene Nanodisk Arrays
Zheyu Fang,Yumin Wang,Andrea E. Schlather,Zheng Liu,Pulickel M. Ajayan,F. Javier García de Abajo,Peter Nordlander,Peter Nordlander,Xing Zhu,Naomi J. Halas +9 more
TL;DR: By incorporating graphene nanodisk arrays into an active device, it is demonstrated that this enhanced absorption efficiency is voltage-tunable, indicating strong potential for nanopatterned graphene as an active medium for infrared electro-optic devices.
Journal ArticleDOI
Narrowband photodetection in the near-infrared with a plasmon-induced hot electron device.
Ali Sobhani,Mark W. Knight,Yumin Wang,Bob Zheng,Nicholas S. King,Lisa V. Brown,Zheyu Fang,Peter Nordlander,Naomi J. Halas +8 more
TL;DR: A grating-based hot electron device with significantly larger photocurrent responsivity than previously reported antenna-based geometries is reported, and the grating geometry enables more than three times narrower spectral response than observed for nanoantenna-based devices.
