Raman Linewidth Contributions from Four-Phonon and Electron-Phonon Interactions in Graphene
Zherui Han, Xiaolong Yang, Sean E. Sullivan +4
The Raman peak position and linewidth provide insight into phonon anharmonicity and electron-phonon interactions (EPI) in materials. For monolayer graphene, prior first-principles…
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…
