The pressure-induced tangential mode Raman peak shifts for single-walled carbon nanotubes (SWNTs) have been studied using a variety of different solvents as hydrostatic pressure-transmitting media. The variation in the nanotube response to hydrostatic pressure with different pressure transmitting media is evidence that the common solvents used are able to penetrate the interstitial spaces in th...

The size and parameter optimization for the 5-nm carbon nanotube field effect transistor (CNFET) static random access memory (SRAM) cell was presented in Part I of this article. Based on that work, we propose a (CNT) SRAM array composed schematically optimized CNFET CNT interconnects. We consider interconnects inside metallic single-wall (M-SWCNT) bundles to represent metal layers 0 1 (M0 M1). ...

Classical molecular dynamics simulations are used to model the bombardment of a bundle of single walled carbon nanotubes by CH3 radicals impacting with incident energies of 10, 45, and 80 eV. The simulations show that there is a high probability of adhesion of either the radicals or their fragments to the nanotube walls at all the incident energies considered. They therefore predict a pathway t...

Degassing of bundles of single-walled carbon nanotubes in vacuum at 500 K is found to drive the thermoelectricpower (TEP) strongly negative, indicating that the degassed metallic tubes in a bundle are n type. The magnitude of the negative TEP indicates that important asymmetry in the electronic carbon pi bands exists near the Fermi energy. Easily measurable increases in the TEP ( approximately ...

Using concepts of hierarchical multi-scale modeling, we report development of a mesoscopic model for single wall carbon nanotubes with parameters completely derived from full atomistic simulations. The parameters in the mesoscopic model are fit to reproduce elastic, fracture and adhesion properties of carbon nanotubes, in this article demonstrated for (5,5) carbon nanotubes. The mesoscale model...

A double-walled carbon nanotube (DWNT) provides the simplest system to study the interaction between concentric layers in carbon nanotubes. The inner and outer walls of a DWNT can be metallic (M) or semiconducting (S), and each of the four possible configurations (M@M, M@S, S@S, S@M) has different electronic properties. Here we report, for the first time, detailed Raman spectroscopy experiments...

Aggregated carbon nanotubes (CNTs) are difficult to be manipulated. Various approaches have been carried out for making nanotube probes, including selection of longest protruding tube from a nanotube aggregate adhered onto substrate [1], direct synthesis of oriented CNTs on a porous surface via metal catalytic pyrolysis [2] and mechanical attachment of CNTs onto an AFM tip under dark-field opti...
