The Phonon dispersion, group velocity, phonon lifetime and scattering rate of 2AL α-PbS under 8.0% tensile strain. The total energy and its derivative changes with external strain. The maximum of energy derivative is larger than 8.0%, which indicates 2AL α-PbS can withstand 8.0% tensile strain. The comparison between DS-PAW and VASP.
