Fig. 4. Anomalous interfacial charge transport.
(A) Sample trajectories for various water volume fraction XH2O (in water/acetone mixture). Localized defects are represented as dots, with the radius corresponding to the localization uncertainty. (B) Evolution of the MSD with time for various water volume fraction XH2O. Green, light blue, dark blue, yellow, and orange correspond to XH2O=1, 0.8, 0.6, 0.4, and 0.2, respectively. (C) Variation of the diffusion coefficient with water volume fraction XH2O. (D) Distribution of the residence time on defects for XH2O = 1 (blue) and XH2O = 0.6 (green). (E) Distribution of the number N of defect sites visited by individual trajectories for varying water fraction. The green dashed line characterizes the exponential decay ∼e−N/N1 with N1 ≈ 3.3.
