Dramatic increase in the thermal boundary conductance and radiation limit from a Nonequilibrium Landauer Approach
Jingjing Shi, Xiaolong Yang, Timothy S. Fisher +1
Thermal boundary conductance (TBC) is critical in many thermal and energy applications. A decades-old puzzle has been that many of the measured TBCs, such as those well characteriz…
Understanding Phonon Scattering by Nano-Precipitates in Potassium-Doped Lead Chalcogenides
Zhao Wang, Xiaolong Yang, Dan Feng +8
We present a comprehensive experimental and theoretical study of phonon scattering by nanoprecipitates in potassium-doped PbTe, PbSe and PbS. We highlight the role of the precipita…
Phonon anharmonic frequency shift induced by four-phonon scattering calculated from first principles
Tianli Feng, Xiaolong Yang, Xiulin Ruan
Phonon energies at finite temperatures shift away from their harmonic values due to anharmonicity. In this paper, we have realized the rigorous calculation of phonon energy shifts…
