nanotubes**

A. Cao and J. Qu, J Appl Phys, 112, 013503 (2012); http://dx.doi.org/10.1063/1.4730908

In this paper, we report a non-equilibrium molecular dynamics study on
the size-dependent thermal conductivity in single-walled carbon
nanotubes with lengths up to micrometers at room temperature. It is
found that the size-dependent thermal conductivity of single-walled
carbon nanotubes can be described by κ(L,d) ≈ κg(L)(1−e−0.185d/a0),
where L is the tube length, d is the diameter, a0 = 2.46 Å is the
graphene lattice constant, and κg(L)∝Lα is the thermal conductivity of
a graphene of length L. In the above, α = 1 for L
