Linear scaling techniques for first-principle calculations of large nanowire devices

Zhang D., Polizzi E., University of Massachusetts, FR

This paper aims to provide a sound basis to face the challenges in large scale atomistic simulations for applications ranging from material sciences and chemistry to nanoelectronics and bio-nanotechnology. In nanoelectronics, large scale ’ab-initio’ simulations [...]

New developments in the purification, filling and functionalisation of carbon nanotubes

Clarke R., Thomas Swan & Company Limited, UK

A substantial body of research has been focused on the preparation of high purity carbon nanotubes (CNT) in a large scale. Subsequently the purified CNTs can then be filled or functionalized depending on the envisaged [...]

Growth of Nanostructured Diamond, Diamond-Like Carbon, and Carbon Nanotubes in a Low Pressure Inductively Coupled Plasma

Okada K., National Institute for Materials Science, JP

A 13.56 MHz low pressure inductively coupled CH4/CO/H2 plasma has been applied to prepare nanocrystalline diamond particles of 200-700 nm diameter. The minimum diameter of the particles was found to be 5 nm. Two-dimensional platelet-like [...]

Diameter Selective Growth of Vertically Aligned Single Walled Carbon Nanotubes by Ethanol Flow Control

Hahm M.G., Noah M.A., Kwon Y., Jung Y.J., Northeastern University, US

The role of ethanol flow rate in CVD process for the diameter control of vertically aligned-SWNTs is presented. Three different flow rates of ethanol (50, 100, and 200 sccm) were supplied to grow VA-SWNTs while [...]

Thermal Stability of Carbon Nanotubes produced by CCVD of Ethylene by using Different Supports

Giraldo L.F., López B.L., Barrera G.M., Universidad de Antioquia, CO

In the synthesis of carbon nanotubes two of the most important parameters to consider are the type of support and the kind of catalytic metal. In this work we have studied the thermal stability of [...]

Low-T Quantum Transport in Carbon Nanotubes: Role of Vacuum Fluctuations in Loss of Phase Coherence

Gabrielli P.G., Gabrielli S., Gabrielli P.G., Gabrielli S., ENEA, IT

Among the items in the design of new generation of electronic devices there are the measurement and understanding of the current-voltage response of an electronic circuit in which molecular systems like carbon nanotubes (CNTs) act [...]

Continuum Modeling the Behavior of Carbon Nanotubes in different load condition

Chaboki A., Sadrnejad S.A., Yahyaiee M., University of Sydney, AU

Molecular dynamics and quantum mechanics are the best method for analysis the CNTs behavior. Bur because of the difficulties and cost, this task is limited to small structure with limited atoms number. In this paper, [...]

Flame synthesis of carbon nanotubes using a double-faced wall stagnation flow burner

Woo S.K., Hong Y-T, Kwon O.C., Sungkyunkwan University, KR

The potential of using a double-faced wall stagnation flow burner in mass production of carbon nanotubes was evaluated experimentally and computationally. With nitrogen-diluted premixed ethylene-air flames established on the Ni-coated stainless steel or Ni-sintered, double-faced [...]

Modeling the Field Emission Current Fluctuation in Carbon Nanotube Thin Films

Sinha N., Roy Mahapatra D., Yeow J.T.W., Melnik R., University of Waterloo, CA

Carbon nanotubes (CNTs) are currently among the best field emitters for a variety of technological applications. However, from mathematical viewpoint, approach towards understanding the physics of nanotube based field emission of a thin film is [...]
