چکیده
Article history: Received 8 January 2010 Received in revised form 9 March 2010 Accepted 2 April 2010 Available online 10 April 2010 Communicated by R. Wu A method for predicting the joule heating using Monte Carlo simulation for the electron dynamics is proposed. The joule heating in (10,10) carbon nanotubes is computed. The full energy band is utilized; however the results show that for low temperatures only the lower subband is sufficient, while for temperatures above 900 K, it is important to include all the subbands. Results are compared with a quantum mechanical integral form which uses an approximation for the electron occupation probability. There is a quantitative agreement of the results; however saturation of the heat generated observed in the integral form is not observed. Published by Elsevier B.V.

A Thermal Model for Carbon Nanotube Interconnects
In this work, we have studied Joule heating in carbon nanotube based very large scale integration (VLSI) interconnects and incorporated Joule heating influenced scattering in our previously developed current transport model. The theoretical model explains breakdown in carbon nanotube resistance which limits the current density. We have also studied scattering parameters of carbon nanotube (CNT)...
متن کاملElectro-Thermal Transport in Silicon and Carbon Nanotube Devices
This work examines electro-thermal transport in silicon devices and in single-wall carbon nanotubes (SWNTs). Non-local transport is found to strongly affect heat generation in quasi-ballistic silicon devices. Under such conditions, Joule heat is mainly dissipated in the drain region, and increasing power densities may lead to phonon non-equilibrium. Significant current degradation is observed i...

Joule heating in single-walled carbon nanotubes CNTs using a quantum mechanical approach is presented in this paper. The modeling is based on the energy transfer between the electrons and both acoustic and optical phonons. In this formulation, only the knowledge of the full energy dispersion relation, phonon dispersion relation, and the electron-phonon coupling potential is required for the cal...
متن کاملBreakdown of Richardson's Law in Electron Emission from Individual Self-Joule-Heated Carbon Nanotubes
Probing the validity of classical macroscopic physical laws at the nanoscale is important for nanoscience research. Herein, we report on experimental evidence that electron emission from individual hot carbon nanotubes (CNTs) heated by self-Joule-heating does not obey Richardson's law of thermionic emission. By using an in-situ multi-probe measurement technique, electron emission density (J) an...
متن کاملLocal control of electric current driven shell etching of multiwalled carbon nanotubes
We report on a novel method for local control of shell engineering in multiwalled carbon nanotubes (MWNTs) using Joule-heating induced electric breakdown. By modulating the heat dissipation along a nanotube, we can confine its thinning and shell breakdown to occur within localized regions of peak temperatures, which are distributed over one-half of the NT length. The modulation is achieved by u...
