Several heat transfer problems related to single-walled carbon nanotubes (SWNTs) are considered using molecular dynamics (MD) simulations. The Brenner potential [1] with the simplified form [2] is employed as the potential function between carbon and carbon within a nanotube. MD simulations of thermal conductivity along a nanotube, isotope effect in longitudinal thermal conductivity, and therma...

Several heat transfer problems related to single-walled carbon nanotubes (SWNTs) are considered using molecular dynamics (MD) simulations. The Brenner potential (Brenner, 1990) with the simplified form (Yamaguchi and Maruyama, 1998) is employed as the potential function between carbon and carbon within a nanotube.

This paper addresses the critical issue of scaling limits of local interconnects, contact plugs and local vias made of metal. It is shown that the current carrying capacity of copper vias/contacts fails to meet ITRS current density requirements beyond the 45 nm technology node. Additionally, the electrical properties of local interconnects/vias made of carbon nanotube (CNT) arrays are analyzed ...

This paper investigates the distortion of DC and radio frequency (RF) pulsed signals in carbon nanotube interconnects. A modified transmission line model for single-walled carbon nanotubes is employed for the simulation. Comparisons with the conventional AlCu interconnect are performed. r 2007 Elsevier Ltd.

Closed-form expressions for the optimized number and size of repeaters in multi-walled carbon nanotube (MWCNT) interconnects are presented. The contact resistance and inductive effects are taken into account. It is found that the propagation delay of MWCNT interconnects can be reduced effectively by inserting repeaters. However, the contact resistance has a significant influence on the optimize...

Several heat transfer problems related to singlewalled carbon nanotubes (SWNTs) are considered through molecular dynamics (MD) simulations. MD simulations of thermal conductivity along a nanotube, isotope effect in longitudinal thermal conductivity, and thermal boundary resistance in a junction of nanotubes are reviewed. Then, the heat transfer from an SWNT to various surrounding materials is s...

Interfacial friction plays a crucial role in the mechanical properties of carbon nanotube based fibers, composites, and devices. Here we use molecular dynamics simulation to investigate the pressure effect on the friction within carbon nanotube bundles. It reveals that the intertube frictional force can be increased by a factor of 1.5-4, depending on tube chirality and radius, when all tubes co...
