  text: The self-assembly of nanoparticles driven by small molecules or ions may produce
    colloidal superlattices with features and properties reminiscent of those of metals
    or semiconductors. However, to what extent the properties of such supramolecular
    crystals actually resemble those of atomic materials often remains unclear. Here,
    we present coarse-grained molecular simulations explicitly demonstrating how a
    behavior evocative of that of semiconductors may emerge in a colloidal superlattice.
    As a case study, we focus on gold nanoparticles bearing positively charged groups
    that self-assemble into FCC crystals via mediation by citrate counterions. In
    silico ohmic experiments show how the dynamically diverse behavior of the ions
    in different superlattice domains allows the opening of conductive ionic gates
    above certain levels of applied electric fields. The observed binary conductive/nonconductive
    behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular
    level, crossing the “band gap” requires a sufficient electrostatic stimulus to
    break the intermolecular interactions and make ions diffuse throughout the superlattice’s
    cavities.
