Journal ArticleDOI
Polyethylene nanofibres with very high thermal conductivities.
TL;DR: The fabrication of high-quality ultra-drawn polyethylene nanofibres with diameters of 50-500 nm and lengths up to tens of millimetres were found and the thermal conductivity was found to be as high as approximately 104 W m(-1) K(-1), which is larger than the conductivities of about half of the pure metals.
Journal ArticleDOI
Spectral Phonon Transport Properties of Silicon Based on Molecular Dynamics Simulations and Lattice Dynamics
Asegun Henry,Gang Chen +1 more
TL;DR: In this article, a combination of equilibrium molecular dynamics simulations and lattice dynamics calculations is used to fully detail the spectral dependence of phonon transport properties in bulk silicon, including the frequency dependence of the specific heat, group velocities and mean free paths.
Journal ArticleDOI
High thermal conductivity of single polyethylene chains using molecular dynamics simulations.
Asegun Henry,Gang Chen +1 more
TL;DR: This work uses molecular dynamics simulations to calculate the thermal conductivity of single polyethylene chains employing both the Green-Kubo approach and a modal decomposition method, suggesting that polymers can be engineered with high thermal Conductivity for a wide variety of applications.
Journal ArticleDOI

TL;DR: Thermal conductivity data suggest that, unlike in drawn crystalline fibres, in the authors' fibres the dominant phonon-scattering process at room temperature is still related to structural disorder, so effective heat transfer at critical contacts in electronic devices operating under high-power conditions at 200 °C over numerous cycles is demonstrated.
Journal ArticleDOI
On the importance of optical phonons to thermal conductivity in nanostructures
TL;DR: In this article, the contribution of different phonon polarizations to the thermal conductivity of silicon is discussed based on the phonon lifetimes extracted from a first-principle approach.
