The complex permittivity from the LMD model fitting ES from Figure is shown in Figure . The zero-crossing of real permittivity from negative to positive at 14 μm is the characteristic of weak localization system. This is theoretically predicted by the localization-modified Drude model with Kramer-Kronig transformation and experimentally observed in weakly localized CPs (Supplementary text 1). For samples with stronger localization, the optical conductivity will significantly decrease (Supplementary Fig. ).
