Synthesis of Carbon Nanotubes by Decomposition of Hydrocarbon Using an Arc-Jet Plasma

Choi S., Choi S.S., Nam J.S., Choi S., Choi S.S., Lee C.M., Kim J.I., Hong S.H., Seoul Nationl University, KR

We present a method to produce carbon nanotubes by decomposition of hydrocarbons using an arc-jet plasma of high temperature (500020000 K). Carbon nanotubes are continuously produced in a floating condition by introducing a hydrocarbon gas [...]

Interaction of Laser Light and Electrons with Nanotubes

Sadeghpour H.R., Granger B.E., Král P., Harvard University, US

Technological leaps of the last two decades have opened windows of opportunity for designing and controlling electronic states in novel systems. The fabrication of quantum dots in semiconductor devices has led to the invention of [...]

Structural and Mechanical Properties of Double Wall Carbon Nanotubes

Bacsa R.R., Bacsa W.S., Flahaut E., Laurent Ch., Peigney A., Puech P., Bacsa R.R., Bacsa W.S., LPST Université Paul Sabatier, FR

Narrow diameter double walled carbon nanotubes can now be grown by the catalytic chemical vapor deposition process with high yield. Double walled carbon nanotubes are the molecular analogs to coaxial cables and they can also [...]

Nano 6H Diamond Polytype Polycrystalline Powder

Ownby P.D., University of Missouri-Rolla, US

In 1967, "Hexagonal diamond - a new form of carbon" was reported to be found in meteorites. This hexagonal form, 2H, was named Lonsdaleite, after the noted crystallographer, Kathleen Lonsdale. Since the corrected structures and [...]

Electrical Property of Fullerene Films Polymerized by Argon Plasma Treatment

Maruyama R., Sony Corporation, JP

Fullerene (C60) is a promising material for nano-carbon device research. Control of the electrical property of C60 is necessary for applications. C60 polymer has great promise because its unique structure allows its electrical and optical [...]

Computing Metallofullerenes as Agents of Nanoscience: Gibbs Energy Treatment of Ca@C72, Ca@C82, and La@C82

Slanina Z., Kobayashi K., Nagase S., Institute for Molecular Science, JP

Various endohedral cage compounds have been suggested as possible candidate species for molecular memories. One approach is built on endohedral species with two possible location sites of the encapsulated atom while another concept of quantum [...]

Self-Assembly of Tetraazamacrocyclic Compounds on Single-Walled Carbon Nanotubes: Experimental and Theoretical Studies

Basiuk E.V., Basiuk V.A., Basiuk E.V., Basiuk V.A., Rybak-Akimova E.V., Acosta-Najarro D., Puente-Lee I., Saniger J.M., Universidad Nacional Autonoma de Mexico, MX

All the existing methods of chemical modification of carbon nanotubes (CNTs) can be divided in two groups, depending on whether functionalizing moieties are introduced onto the nanotube tips or sidewalls. The latter approach offers wider [...]

Investigation of Robust Fully-Silicided NMOSFETs for Sub-100 nm ESD Protection Circuits Design

Lee J.W., Tang H., Li Y., Natl Nano Device Labs & Natl Chiao Tung Univ, TW

Electrostatic discharge (ESD) becomes an important issue in vary large scaled integrated (VLSI) circuit design and manufacture, especially for the ultra-thin oxide nano-devices [1-3]. It results from a fact that the gate oxide will be [...]

Defects and Fault Characterization in Quantum Cellular Automata

Baradaran Tahoori M., Momenzadeh M., Huang J., Lombardi F., Northeastern University, US

In this paper, a detailed simulation-based characterization of QCA defects and study of their effects at logic-level are presented. Different defect mechanisms for QCA active devices and interconnects are considered and the appropriate fault models [...]

A Nanoscale Electromechanical Contact Switch for Logic Applications

Huang C-C, Ekinci K.L., Boston University, US

Here, we describe the operation of a nano-electro-mechanical contact switch. The switch design relies on a sharp contact tip integrated to a compliant nanomechanical beam. When the beam is actuated electrostatically, the tip establishes intimate [...]
