PhonoMC: Occupation-based deviational Monte Carlo for phonon transport with temperature-dependent scattering
Shixian Liu, Fei Yin, Gang Wang +4
Nanoscale self-heating involves phonon transport across confined geometries, material interfaces, and temperature fields over which the scattering rates can vary substantially. We…

Knudsen-Controlled Switching of Thermal Conductivity Response by Targeted Phonon Excitation
Shixian Liu, Tianhao Li, Fei Yin +4
Targeted phonon excitation offers a route to dynamically control heat conduction, yet no general principle predicts whether a spectrally selective nonequilibrium phonon population…
