Anomalous transverse optic phonons in SnTe and PbTe -- revisited
Zehua Li, Shasha Li, John-Paul Castellan +5
We present a study of the soft transverse optic phonon mode in SnTe in comparison to the corresponding mode in PbTe using inelastic neutron scattering and ab-initio lattice dynamic…
Thermal diffusivity and its lower bound in orthorhombic SnSe
Valentina Martelli, Fabio Abud, Julio Larrea Jiménez +3
The orthorhombic monochalcogenide SnSe has attracted much attention in recent years as a promising high-temperature thermoelectric material. We present a study of its thermal condu…
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…
