From the j it is also possible to estimate the resistivity of this superlattice against the CIT ionic current according to the Ohm law, ρ = |E/j|. Figure , which reports ρ as a function E, coherently shows how the resistivity decreases with increasing the temperature in the system. These results underline another difference between such superlattices and pure metals, where increasing the temperature typically produces an increase in the resistivity and a drop in the conductivity. This discrepancy arises from the different physical nature of the "supramolecular" ionic conductivity in this superlattice vs. electronic conductivity in metals. In our superlattices, the former is ruled by classical intermolecular interactions, while metals are governed by the quantum behavior of free-electrons. Despite such clear differences, it is interesting to note how the estimated ρ for the TMA-NP superlattice ranges between ∼ 10 -5 and ∼ 10 5 Ω m, in the typical regime of semiconductor materials. The binary non-conductive/conductive behavior as a function of E also is reminiscent of the behavior of semiconductors. It seems that a sufficient electric stimulus (E ∼ 0.05 V nm -1 ) must be provided to the system -generating a sufficiently strong electric force F = qE acting on the CIT ions -to break the electrostatic interaction between the CITs and the positively charged TMA groups, and to make the ions free to move and diffuse in the lattice. This behavior is analogous to crossing the "band-gap" and turning the material from non-conductive to conductive. In general, while these superlattices present a behavior more similar to that of semiconductors than to metals, these models also offer the possibility to deeply penetrate into these systems to investigate the mechanisms that control their conductive properties.
