Thermoelectric transport properties of silicon: Towards an ab initio approach
Z. Wang, S. Wang, S. Obukhov +4
We have combined the Boltzmann transport equation with an {\it ab initio} approach to compute the thermoelectric coefficients of semiconductors. Electron-phonon, ionized impurity,…
Breakdown of Herring's processes in cubic semiconductors for sub-terahertz longitudinal acoustic phonons
Maxime Markov, Jelena Sjakste, Nathalie Vast +3
In the present work we explain the anomalous behavior of the attenuation of the longitudinal acoustic phonon in GaAs as a function of the phonon energy in the sub-THz domain. T…
Hydrodynamic heat transport regime in bismuth: a theoretical viewpoint
Maxime Markov, Jelena Sjakste, Giuliana Barbarino +5
Bismuth is one of the rare materials in which second sound has been experimentally observed. Our exact calculations of thermal transport with the Boltzmann equation predict the occ…
