Thermal conductivity of individual silicon nanowires
TL;DR: The thermal conductivities of individual single crystalline intrinsic Si nanowires with diameters of 22, 37, 56, and 115 nm were measured using a microfabricated suspended device over a temperature range of 20-320 K as discussed by the authors.

Microscale Heat Conduction in Dielectric Thin Films
TL;DR: Based on Boltzmann transport theory, an equation of phonon radiative transfer (EPRT) was developed in this paper, where the phonon-scattering mean free path was used to analyze heat transport by lattice vibrations or phonons.

Phonon heat conduction in a semiconductor nanowire
Jie Zou,Alexander A. Balandin +1 more
TL;DR: In this article, a model for phonon heat conduction in a semiconductor nanowire with dimensions comparable to the phonon mean free path is developed based on the solution of Boltzmann's equation, which takes into account modification of the acoustic phonon dispersion due to spatial confinement, and change in the nonequilibrium phonon distribution due to partially diffuse boundary scattering.
