Green's Functions of the Boltzmann Transport Equation with the Full Scattering Matrix for Phonon Nanoscale Transport beyond the Relaxation Time Approximation
Vazrik Chiloyan, Samuel Huberman, Zhiwei Ding +4
The phonon Boltzmann transport equation (BTE) has been widely utilized to study thermal transport in solids. While for a number of materials the exact solution to the BTE has been…
Nondiffusive thermal transport from micro/nanoscale sources producing nonthermal phonon populations exceeds Fourier heat conduction
Vazrik Chiloyan, Samuel Huberman, Alexei A. Maznev +2
We study nondiffusive thermal transport by phonons at small distances within the framework of the Boltzmann transport equation (BTE) and demonstrate that the transport is significa…
study of electron mean free paths and thermoelectric properties of lead telluride
Qichen Song, Te-Huan Liu, Jiawei Zhou +2
Last few years have witnessed significant enhancement of thermoelectric figure of merit of lead telluride (PbTe) via nanostructuring. Despite the experimental progress, current und…
Unifying first principle theoretical predictions and experimental measurements of size effects on thermal transport in SiGe alloys
Samuel Huberman, Vazrik Chiloyan, Ryan A. Duncan +6
In this work, we demonstrate the correspondence between first principle calculations and experimental measurements of size effects on thermal transport in SiGe alloys. Transient th…
Thermal transport in suspended silicon membranes measured by laser-induced transient gratings
Alejandro Vega-Flick, Ryan A. Duncan, Jeffrey K. Eliason +12
Studying thermal transport at the nanoscale poses formidable experimental challenges due both to the physics of the measurement process and to the issues of accuracy and reproducib…
Thermal Conductivity of GaAs/Ge Nanostructures
Roger Jia, Lingping Zeng, Gang Chen +1
Superlattices are promising low-dimensional nanomaterials for thermoelectric technology that is capable of directly converting low-grade heat energy to useful electrical power. In…
