Lattice vibrations in crystalline materials generate phonons as heat carriers for heat conduction, and the phonon dispersion (energy versus momentum) is fundamentally determined by the mass of lattice vibrators

Maximizing band degeneracy and minimizing phonon relaxation time are proven to be successful for advancing thermoelectrics. Alloying with monotellurides has been known to be an effective approach for converging the valence bands of PbTe for electronic improvements, while the lattice thermal conductivity ...

our high-resolution NPD patterns indicate that Sr2ZnSb2has a much stronger strain field as it exhibits a larger Bragg peak width than Sr(Cu,Ag)Sb (Supplementary Fig.17). Therefore, the vacancies in Sr2ZnSb2should also play a role in phonon-point defect scattering in addition to softening th...
