Journal ArticleDOI
Uniform patterned growth of carbon nanotubes without surface carbon
Kenneth B. K. Teo,Manish Chhowalla,Gehan A. J. Amaratunga,William I. Milne,David G. Hasko,G. Pirio,Pierre Legagneux,F. Wyczisk,Didier Pribat +8 more
TL;DR: In this paper, the authors demonstrate a technique that enables high yield, uniform, and preferential growth of perfectly aligned carbon nanotubes by using plasma-enhanced chemical-vapor deposition (PECVD).
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
Use of ZnO thin films as sacrificial templates for metal organic vapor phase epitaxy and chemical lift-off of GaN
D. J. Rogers,F. Hosseini Teherani,Abdallah Ougazzaden,Simon Gautier,Laurent Divay,Alain Lusson,Olivier Durand,Olivier Durand,F. Wyczisk,G. Garry,Teresa Monteiro,M. R. Correira,Marco Peres,A.J. Neves,Damien McGrouther,J. N. Chapman,Manijeh Razeghi +16 more
TL;DR: In this article, GaN was grown on ZnO/c-Al2O3 using low temperature/pressure MOVPE with N2 as a carrier and dimethylhydrazine as a source.
Journal ArticleDOI
Growth of high-quality single-wall carbon nanotubes without amorphous carbon formation
Rodrigo G. Lacerda,Aun Shih Teh,M. H. Yang,Kenneth B. K. Teo,Nalin L. Rupesinghe,S. H. Dalal,Krzysztof K. K. Koziol,Debdulal Roy,Gehan A. J. Amaratunga,William I. Milne,Manish Chhowalla,David G. Hasko,F. Wyczisk,Pierre Legagneux +13 more
TL;DR: In this paper, a triple-layer thin film of Al/Fe/Mo (with Fe as a catalyst) on an oxidized Si substrate is exposed to a single short burst (5 s) of acetylene at 1000°C.
Journal ArticleDOI
Characterization of plasma-enhanced chemical vapor deposition carbon nanotubes by Auger electron spectroscopy
Kbk Teo,Manish Chhowalla,Gehan A. J. Amaratunga,William I. Milne,G. Pirio,Pierre Legagneux,F. Wyczisk,J. Olivier,Didier Pribat +8 more
TL;DR: In this paper, the authors report on the characterization of PECVD deposited nanotubes using Auger Electron Spectroscopy (AES) and show that by adjusting the deposition gas ratios, using depth-profiled composition analysis, it is possible to eliminate the unwanted amorphous carbon on the substrate surface.
