The Electronic Thermal Conductivity of Graphene [PDF]

open access: yesNano Letters, 2016
Graphene, as a semimetal with the largest known thermal conductivity, is an ideal system to study the interplay between electronic and lattice contributions to thermal transport. While the total electrical and thermal conductivity have been extensively investigated, a detailed first-principles study of its electronic thermal conductivity is still ...

Propagating elastic vibrations dominate thermal conduction in amorphous silicon [PDF]

open access: yes, 2017
The thermal atomic vibrations of amorphous solids can be distinguished by whether they propagate as elastic waves or do not propagate due to lack of atomic periodicity.

Suppression of Electron Thermal Conduction by Whistler Turbulence in a Sustained Thermal Gradient. [PDF]

open access: yesPhysical Review Letters, 2017
The dynamics of weakly magnetized collisionless plasmas in the presence of an imposed temperature gradient along an ambient magnetic field is explored with particle-in-cell simulations and modeling.

Cross-Plane Thermal Transport in Layered Materials [PDF]

open access: yesarXiv, 2023
The cross-plane (across-layers) phonon thermal transport of five diverse, layered semiconductors is investigated by accounting for higher-order four-phonon scattering, phonon renormalization, and multi-channel thermal transport. For materials having relatively large cross-plane thermal conductivity (AlB6, MoS2, and MoSi2N4), phonons contributing to ...

Thermal conduction across a boron nitride and SiO2 interface [PDF]

open access: yes, 2017
The need for efficient heat removal and superior thermal conduction in nano/micro devices has triggered tremendous studies in low-dimensional materials with high thermal conductivity. Hexagonal boron nitride (h-BN) is believed to be one of the candidates

Phonon thermal conduction in novel 2D materials [PDF]

open access: yesJournal of Physics: Condensed Matter, 2016
Recently, there has been increasing interest in phonon thermal transport in low-dimensional materials, due to the crucial importance of dissipating and managing heat in micro- and nano-electronic devices.

Tunable Thermal Conduction in Graphane Nanoribbons [PDF]

open access: yes, 2014
Graphane and graphene are both two-dimensional materials but of different bonding configurations, which can result in distinct thermal conduction properties. We simulate thermal conduction in graphane nanoribbons (GANRs) using the nonequilibrium Green's function method.

THE LAUNCHING OF COLD CLOUDS BY GALAXY OUTFLOWS. II. THE ROLE OF THERMAL CONDUCTION [PDF]

open access: yes, 2016
We explore the impact of electron thermal conduction on the evolution of radiatively cooled cold clouds embedded in flows of hot and fast material as it occurs in outflowing galaxies.

Thermal conductivity of antigorite

open access: yes, 2023
This repository contains experimental data on the thermal conductivity of antigorite at high pressures and temperatures as well as a self-written MATLAB script used to numerically model 2D thermal evolution of a sinking slab. These materials are presented in a manuscript submitted by Yu-Hsiang Chien, Enrico Marzotto, Yi-Chi Tsao, and Wen-Pin Hsieh ...

Anisotropic Thermal Conduction in Supernova Remnants: Relevance to Hot Gas Filling Factors in the Magnetized ISM

open access: yes, 2006
We explore the importance of anisotropic thermal conduction in the evolution of supernova remnants via numerical simulations. The mean temperature of the bubble of hot gas is decreased by a factor of ~3 compared to simulations without thermal conduction,
