Electron-induced non-monotonic pressure dependence of the lattice thermal conductivity of θ-TaN
Ashis Kundu, Yani Chen, Xiaolong Yang +5
Recent theoretical and experimental research suggests that -TaN is a semimetal with high thermal conductivity (), primarily due to the contribution of phonons ($κ_\texttt{ph}…
Raman Linewidth Contributions from Four-Phonon and Electron-Phonon Interactions in Graphene
Zherui Han, Xiaolong Yang, Sean E. Sullivan +4
The Raman peak position and linewidth provide insight into phonon anharmonicity and electron-phonon interactions (EPI) in materials. For monolayer graphene, prior first-principles…
FourPhonon: An extension module to ShengBTE for computing four-phonon scattering rates and thermal conductivity
Zherui Han, Xiaolong Yang, Wu Li +2
FourPhonon is a computational package that can calculate four-phonon scattering rates in crystals. It is built within ShengBTE framework, which is a well-recognized lattice thermal…
Combined treatment of phonon scattering by electrons and point defects explains the thermal conductivity reduction in highly-doped Si
Bonny Dongre, Jesús Carrete, Shihao Wen +4
The mechanisms causing the reduction in lattice thermal conductivity in highly P- and B-doped Si are looked into in detail. Scattering rates of phonons by point defects, as well as…
Optimizing phonon scattering by tuning surface-interdiffusion-driven intermixing to break the random-alloy limit of thermal conductivity
Xiaolong Yang, Wu Li
We investigate the evolution of the cross-plane thermal conductivity of superlattices (SLs) as interfaces change from perfectly abrupt to totally intermixed, by using non-equil…
Significant reduction of lattice thermal conductivity in suspended graphene by charge doping
Ajit Jena, Wu Li
Declining the lattice thermal conductivity in graphene is essential for its thermoelectric applications. In high electron density systems, scatterings of phonons by electrons are n…
