Figure 3.

Temperature-dependence of (a) effective THz charge-carrier mobilities and (b) charge-carrier localization rates extracted from the two-level mobility model discussed in the main text. The values of μ_deloc for the lowest four temperatures were not included in the power-law fit, as this relation diverges unphysically as T → 0. The dashed line in (b) indicates the mean value of k_loc = 0.65 ± 0.05 ps^–1 across all temperatures, showing the lack of temperature dependence of the self-trapping process.
