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 [...]

Individual Carbon Nanotube Cold Field Emitters: Experimental and Modeling Studies of Integrated System Architecture

Niemann D.L., Ribaya B.P., Gunther N., Rahman M., Leung J., Nguyen C.V., Eloret Corp, NASA Ames Research Center, US

Individual carbon nanotube (CNT) cold field emitters are promising point electron sources because of their low energy spread, high brightness, and low power consumption [1-3]. Potential high-resolution applications for these efficient electron sources include advanced [...]

Coulomb Oscillations at Room-Temperature of Single-Walled Carbon Nanotube Field-Effect Transistors

Ohno Y., Asai Y., Maehashi K., Inoue K., Matsumoto K., Osaka University, JP

Single-walled carbon nanotube field-effect transistors with thin tunnel barriers were investigated, and room-temperature single-electron transistor (SET) operation was realized. Single-walled carbon nanotubes were grown by thermal chemical vapor deposition at 820 degrees Celsius for 10 [...]
