Figure 4.

Color online. Three-dimensional model: Nosé-Hoover thermostats are coupled to the end atoms of a (5, 5) SWNT. Both bonded (8), (9), and (10), and non-bonded interactions (11) are considered. In a three-dimensional structure, harmonic-bonded potentials do give rise to normal heat conduction. Temperature profiles for two lengths (5.5 and 10 nm) are reported.
