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…
