TL;DR: In this paper, the Boltzmann transport equation under the relaxation-time approximation was used to calculate the thermoelectric properties of $n$-type and $p$ -type SiGe nanocomposites.

TL;DR: A method is presented that can accurately reconstruct the MFP distribution from quasiballistic thermal measurements without any assumptions regarding the phonon scattering mechanisms, which will enable a substantially improved understanding of thermal transport in many solids, particularly thermoelectrics.

TL;DR: In this article, the authors introduce the quantum imaginary time evolution and quantum Lanczos algorithms, which are analogues of classical algorithms for finding ground and excited states, and demonstrate the potential of these algorithms via an implementation using exact classical emulation as well as prototype circuits on the Rigetti quantum virtual machine and Aspen-1 quantum processing unit.

TL;DR: Recent advances in both computation and experiment are enabling an unprecedented microscopic view of thermal transport by phonons in both bulk and nanostructured crystals, from the level of atomic bonding to mesoscopic transport in complex devices.

TL;DR: In this article, the authors showed that a higher Yb concentration not only increases the power factor due to a higher electron concentration but also reduces the thermal conductivity $k$ because of stronger phonon scattering.
