Isotope Effects on Heat Conduction of Carbon Nanotubes
We have been studying the heat conduction along a single-walled carbon nanotube (SWNT) by the molecular dynamics method with the Tersoff-Brenner bond order potential [1, 2]. It is well known that the inclusion of only 1 % of C natural isotope dramatically reduces the thermal conductivity of diamond. However, isotope effects on heat conduction of SWNTs have not been elucidated. We estimated isot...
متن کاملMolecular dynamics simulations of heat conduction in multi-walled carbon nanotubes
Heat conduction in multi-walled carbon nanotubes (MWNTs) was studied using non-equilibrium molecular dynamics simulations. This research focuses on the effects of the multi-wall structure of the MWNTs on the heat conduction. The results show that the thermal conductivity of a MWNT is almost the same as that of the corresponding single-walled carbon nanotubes (SWNTs) rather than much smaller as ...
متن کاملDiffusive-Ballistic Heat Conduction of Carbon Nanotubes and Nanographene Ribbons
Investigations of diffusive-ballistic heat conduction of finite-length single-walled carbon nanotubes and nanographene ribbons at room temperature have been carried out by using nonequilibrium molecular dynamics simulations. The length dependences of thermal conductivity reveal the variation of the balance between ballistic and diffusive heat conduction. For both systems, the profile indicates ...
متن کاملMolecular Dynamics Simulations of Heat Transfer Issues in Carbon Nanotubes
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...
متن کاملMolecular Dynamics Simulations of Heat Transfer of Carbon Nanotubes
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...
