FourPhonon: An extension module to ShengBTE for computing four-phonon scattering rates and thermal conductivity
Zherui Han, Xiaolong Yang, Wu Li +2
FourPhonon is a computational package that can calculate four-phonon scattering rates in crystals. It is built within ShengBTE framework, which is a well-recognized lattice thermal…
Atomistic metrics of BaSO as an ultra-efficient radiative cooling material: a first-principles prediction
Zhen Tong, Joseph Peoples, Xiangyu Li +3
Radiative cooling has recently revived due to its significant potential as an environmentally friendly cooling technology. However, the design of particle-matrix cooling nanocompos…
Optimizing phonon scattering by tuning surface-interdiffusion-driven intermixing to break the random-alloy limit of thermal conductivity
Xiaolong Yang, Wu Li
We investigate the evolution of the cross-plane thermal conductivity of superlattices (SLs) as interfaces change from perfectly abrupt to totally intermixed, by using non-equil…
Four-phonon scattering diminishes the optical phonon contribution and isotope effect to thermal conductivity of III-V semiconductors
Xiaolong Yang, Tianli Feng, Ju Li +1
Recent studies reveal that four-phonon scattering is generally important in determining thermal conductivities of solids. However, these studies have been focused on materials wher…
Role of higher-order phonon scattering in the zone-center optical phonon linewidth and the Lorenz oscillator model
Xiaolong Yang, Tianli Feng, Joon Sang Kang +3
Zone-center optical phonon linewidth is a key parameter for infrared and Raman spectra as well as the Lorenz oscillator model. While three-phonon scattering was often assumed to be…
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…
