Assemblies of chemically precise nanoclusters have recently been synthesised to demonstrate the dependence of electronic transport properties on structural order[1]. The nanoclusters themselves are examples of superatomic species for which the electronic structure can be understood as emerging from the valence electrons of the metal atoms. The interactions between these emergent superatomic states leads to the observed electronic transport properties.
We apply the kinetic monte carlo method to study carrier transport in crystalline and amorphous assemblies of nanoclusters. In doing so we can compare directly to experimental observations of the conductance anisotropy and its temperature response.
