Hisato Yamaguchi,Katsuhisa Murakami,Katsuhisa Murakami,Goki Eda,Takeshi Fujita,Pengfei Guan,Weichao Wang,Cheng Gong,Julien Boisse,Steve Miller,Muge Acik,Kyeongjae Cho,Yves J. Chabal,Mingwei Chen,Fujio Wakaya,M. Takai,Manish Chhowalla +16 more
TL;DR: In this article, the authors reported low threshold field emission of multiple electron beams from atomically thin edges of reduced graphene oxide (rGO) point sources by using high-resolution transmission electron microscopy, infrared spectroscopy and simulation results.
Journal ArticleDOI
Improvement in electron emission from carbon nanotube cathodes after Ar plasma treatment
TL;DR: In this paper, a CNT cathode was exposed to Ar plasma for 3 min, and the emission characteristics were improved by three orders of magnitude from 9.0×10−5 to 3.3× 10−1 mA/cm2 at 4.0 V/μm.
Journal ArticleDOI

TL;DR: In this paper, a single layer of graphene with dimensions of 20mm and 20mm was grown directly on an insulating substrate by chemical vapor deposition using Ga vapor catalysts, and the crystal quality of the graphene was measured by Raman spectroscopy and was found to improve with increasing Ga vapor density on the reaction area.
Journal ArticleDOI
Transport properties of pt nanowires fabricated by beam induced deposition
TL;DR: In this article, the electron-beam and focused-ion-beam (FIB)-induced deposition of Pt nanowires was investigated and the observed temperature dependence of the resistance of the EB-deposited wires indicates that the electron transport in the wires is dominated by variable range hopping (VRH).
