The hQSGW and PBE0 computational methodologies were consistent with the calculations described above. To obtain the transport properties and scattering rates, the electronic band structure and wave function coefficients were interpolated onto a dense 87 × 87 × 45 k-point mesh. One benefit of AMSET compared to state-of-the-art approaches based on density functional perturbation theory combined with Wannier interpolation (DFPT+Wannier) is that scattering rates can be obtained from common materials parameters without requiring an expensive DFPT calculation. The calculated materials parameters (dielectric constants, polar phonon frequency, and elastic constants) along with additional settings used by amset are provided in the Supporting Information. The full AMSET methodology, including the scattering matrix elements and interpolation scheme is given in detail in Ref. 35.
