Growth of aligned SWNT arrays from water-soluble molecular clusters for nanotube device fabrication
A simple method to fabricate parallel and/or crossed networks of ultra-long single-walled carbon nanotube (SWNT) arrays based on carbon monoxide-chemical vapor deposition (CO-CVD) by a ‘‘ fast-heating ’’ growth process is reported. The catalysts which are water-soluble inorganic molecular clusters containing Fe and Mo atoms can be easily ‘‘drawn’’ on the substrate by an ink pen using the cluste...
متن کاملNumerical Analysis of Inlet Gas-Mixture Flow Rate Effects on Carbon Nanotube Growth Rate
The growth rate and uniformity of Carbon Nano Tubes (CNTs) based on Chemical Vapor Deposition (CVD) technique is investigated by using a numerical model. In this reactor, inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal CVD reactor at atmospheric pressure. Based on the gas phase and surface reactions, released carbon...
متن کاملComparison between Copper and Iron as Catalyst for Chemical Vapor Deposition of Horizontally Aligned Ultralong Single-Walled Carbon Nanotubes on Silicon Substrates
A careful comparison was performed between Cu and Fe as catalysts for the growth of horizontally aligned ultralong single-walled carbon nanotube (SWNT) arrays on SiOx/Si substrates, and the mechanism of the difference was discussed. Cleaner and straighter SWNTs with smaller diameters and narrower size distribution were obtained using Cu as catalyst. It was also found that the SWNTs always grew ...
متن کاملCarbon nanotube atomic force microscopy tips: direct growth by chemical vapor deposition and application to high-resolution imaging.
Carbon nanotubes are potentially ideal atomic force microscopy probes because they can have diameters as small as one nanometer, have robust mechanical properties, and can be specifically functionalized with chemical and biological probes at the tip ends. This communication describes methods for the direct growth of carbon nanotube tips by chemical vapor deposition (CVD) using ethylene and iron...
متن کاملLarge Scale CVD Synthesis of Single-Walled Carbon Nanotubes
The synthesis of bulk amounts of high quality single-walled carbon nanotubes (SWNTs) is accomplished by optimizing the chemical compositions and textural properties of the catalyst material used in the chemical vapor deposition (CVD) of methane. A series of catalysts are derived by systematically varying the catalytic metal compounds and support materials. The optimized catalysts consist of Fe/...
