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…

Higher-Order-Phonon Scattering Governs Targeted Control of Heat Conduction in Bulk Boron Arsenide
Tianhao Li, Yangjun Qin, Dongkai Pan +3
Conventional approaches for modulating thermal conductivity usually rely on structural modifications and therefore cannot achieve reversible in situ regulation. Targeted phonon exc…
