Densification of single-walled carbon nanotube films: Mesoscopic distinct element method simulations and experimental validation

Thermoelectric power of single-walled carbon nanotube films

We report measurements of the thermoelectric power ~TEP! S and electrical resistance R of thin films of tangled ropes of single-walled carbon nanotubes. Experiments at 300 K under applied force normal to the plane of the film revealed a ;10–20 % decrease in the four-probe resistance, indicating that the contact resistance between ropes had improved. The TEP, however, was not affected by the app...

Bolometric infrared photoresponse of suspended single-walled carbon nanotube films.

The photoresponse in the electrical conductivity of a single-walled carbon nanotube (SWNT) film is dramatically enhanced when the nanotube film is suspended in vacuum. We show here that the change in conductivity is bolometric (caused by heating of the SWNT network). Electron-phonon interactions lead to ultrafast relaxation of the photoexcited carriers, and the energy of the incident infrared (...

Single-Walled Carbon Nanotube Electronics

Single walled carbon nanotubes (SWNTs) have emerged as a very promising new class of electronic materials. The fabrication and electronic properties of devices based on individual SWNTs are reviewed. Both metallic and semiconducting SWNTs are found to possess electrical characteristics that compare favorably to the best electronic materials available. Manufacturability issues, however, remain a...

Aligned Growth of Single-Walled and Double- Walled Carbon Nanotube Films by Control of Catalyst Preparation

Young s Modulus of Single and Double Walled Carbon Nanocones Using Finite Element Method(TECHNICAL NOTE)

In this paper a three-dimensional finite element (FE) model of carbon nanocones (CNCs) is proposed and used for obtaining Young\'s modulus of CNCs. In this model, stretching and bending forces between carbon atoms are simulated using truss elements in ANSYS software. Then the model is subjected to the tension and by obtaining the stiffness of the CNC and using elasticity theory, Young’s modulus...
