Fig. 19

Computed average relaxation times of electrons and holes for the 12 compounds in Set D. For completeness, we also show data for the 4 additional compounds included in Fig. 18. The average relaxation time τ is obtained from Drude’s formula via the computed aiBTE mobilities μ and conductivity effective masses m*, τ = μm*/e (e is the electron charge). For comparison, we also show the simple estimate via Emin’s formula (thick horizontal line).
