Journal ArticleDOI
Properties of carbon onions produced by an arc discharge in water
Noriaki Sano,Haolan Wang,Ioannis Alexandrou,Manishkumar Chhowalla,Kbk Teo,Gehan A. J. Amaratunga,Kenji Iimura +6 more
TL;DR: In this article, a simple method to fabricate high quality nanoparticles including spherical carbon onions and elongated fullerene-like nanoparticles similar to nanotubes in large quantities without the use of vacuum equipment is reported.
Journal ArticleDOI
Field emission from dense, sparse and patterned arrays of carbon nanofibers
Kbk Teo,Manish Chhowalla,Gehan A. J. Amaratunga,William I. Milne,G. Pirio,Pierre Legagneux,F. Wyczisk,Didier Pribat,David G. Hasko +8 more
TL;DR: In this article, the authors compared the field emission characteristics of vertically aligned carbon nanofibers on silicon substrates and showed that the patterned array of individual vertically aligned nanofiber had the most desirable field emission properties, highest apparent field enhancement factor, and emission site density.
Journal ArticleDOI
Plasma enhanced chemical vapour deposition carbon nanotubes/nanofibres - How uniform do they grow?
Kbk Teo,Shinbuhm Lee,Manishkumar Chhowalla,V. Semet,Vu Thien Binh,O. Groening,M. Castignolles,A. Loiseau,G. Pirio,Pierre Legagneux,Didier Pribat,David G. Hasko,Haroon Ahmed,Gehan A. J. Amaratunga,William I. Milne +14 more
TL;DR: In this article, the structural uniformity of carbon nanotubes/nanofibres (CNs) produced by plasma enhanced chemical vapour deposition is evaluated for field emission applications.
Journal ArticleDOI
Fabrication and electrical characteristics of carbon nanotube field emission microcathodes with an integrated gate electrode
G. Pirio,Pierre Legagneux,Didier Pribat,Kbk Teo,Manish Chhowalla,Gehan A. J. Amaratunga,William I. Milne +6 more
TL;DR: In this paper, a self-aligned fabrication process was used to ensure that the carbon nanotubes were always centred with respect to the gate apertures (2 µm diameter) over the entire device.
Book Chapter
Catalytic synthesis of carbon nanotubes and nanofibers
TL;DR: In this article, the authors use the term nanotube to describe carbon filaments with tubular graphene walls parallel to the axis and use the terms nanofiber for carbon filament with graphene layers at other angles.
