Coupling between Phonon-Phonon and Phonon-Impurity Scattering: A Critical Revisit of the Spectral Matthiessen's Rule
Tianli Feng, Bo Qiu, Xiulin Ruan
The spectral Matthiessen's rule is commonly used to calculate the total phonon scattering rate when multiple scattering mechanisms exist. Here we predict the spectral phonon relaxa…
Ab initio optimization of phonon drag effect for lower-temperature thermoelectric energy conversion
Jiawei Zhou, Bolin Liao, Bo Qiu +4
While the thermoelectric figure of merit zT above 300K has seen significant improvement recently, the progress at lower temperatures has been slow, mainly limited by the relatively…
Ab initio study of electron-phonon interaction in phosphorene
Bolin Liao, Jiawei Zhou, Bo Qiu +2
The monolayer of black phosphorous, or phosphorene, has recently emerged as a new 2D semiconductor with intriguing highly anisotropic transport properties. Existing calculations of…
Significant reduction of lattice thermal conductivity by electron-phonon interaction in silicon with high carrier concentrations: a first-principles study
Bolin Liao, Bo Qiu, Jiawei Zhou +3
Electron-phonon interaction has been well known to create major resistance to electron transport in metals and semiconductors, whereas less studies were directed to its effect on t…
First-Principles Simulation of Electron Mean-Free-Path Spectra and Thermoelectric Properties in Silicon
Bo Qiu, Zhiting Tian, Ajit Vallabhaneni +5
The mean-free-paths (MFPs) of energy carriers are of critical importance to the nano-engineering of better thermoelectric materials. Despite significant progress in the first-princ…
Molecular dynamics simulations of thermal conductivity and spectral phonon relaxation time in suspended and supported graphene
Bo Qiu, Xiulin Ruan
We perform molecular dynamics (MD) simulations with phonon spectral analysis aiming at understanding the two dimensional (2D) thermal transport in suspended and supported graphene.…
