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…
The substitutional atomic distance model for predicting lattice thermal conductivity in alloys
Zhicheng Zong, Tianhao Li, Shixian Liu +2
Understanding phonon transport in alloys is crucial for the design of high-performance electronic and thermoelectric devices. However, conventional theoretical models fail to provi…
Effect of non-Fourier heat transport on temperature distribution in High Bandwidth Memory
Zhihao Zhou, Yu He, Shixian Liu +2
High Bandwidth Memory (HBM), as a key development trend in future memory chip technology, significantly enhances computer performance. At the same time, the thermal challenges aris…
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…
