By monitoring the overall CIT ions dynamics at different E intensities, it is possible to compare the effect of the electrostatic stimulus on the internal dynamics of the EAs. Figure (right) shows how CIT ions, initially colored with a color palette from red to blue, based on their x position in the simulation box, reshuffle in the superlattice during the MD at E = 0.09 V nm -1 . The MD snapshots in Figure also demonstrate how at T = 300 K the CIT reshuffling changes with the intensity of E (all the systems share the same initial configuration): the higher the deviation from the initial color pattern, the more significant the CIT diffusion along the E direction (x axis). In particular, while weaker Es (e.g., E = 0 and E = 0.01 V nm -1 ) appear to have little effect on the CIT dynamics, increasing the E intensity (e.g., E = 0.11 V nm -1 or 0.09 V nm -1 ) notably enhances the CIT reshuffling during the same sampled CG-MD regimes. A similar behavior is observed at T = 333 K, while in this case the mobility of the CIT ions is in general increased with respect to T = 300 K due to the stronger thermal agitation (see Supplementary Figure ).
