To obtain a more direct evidence into what extent such EA mobility in a superlattice produces features typical of, e.g., metallic or covalent crystals, we designed an ad hoc ohmic in silico experiment. Using previously validated implicit-solvent CG models, which guarantee relatively high-resolution (< 5 Å) and good consistency with chemically relevant all-atom models, we created a model FCC lattice. The simulated box is composed of four NPs decorated with 804 positively charged TMA groups each, arranged in such a way as to produce, when replicated in three dimensions via periodic boundary conditions (PBC), an infinite FCC lattice consistent with the experimentally obtained lattice parameters. In the FCC cell model, the TMA-NPs are surrounded by 1072 -3e charged CIT counterions. The basic idea is that the application of a homogeneous directional electric field (E, oriented along x direction) allows monitoring the diffusion of CIT ions within the TMA-NP superlattice and reconstructing the diffusion mechanisms (Figure : left and center). Details on the molecular models and on the simulation protocols are provided in the Methods section.
