    • The renormalization of the single-electron energy levels combined with the slow relaxation of excited electrons within the nanograin is the source of complexity of the master (Boltzmann) equation. At a given applied bias voltage V, several configurations that belong to different generations carry the current through the nanograin. As the generations form a hierarchy, the rate equations couple different eh-pair subspaces. Furthermore, these couplings would be different depending on the value of V as different single-electron energy levels posses different individual tunneling in and out rates (see Ref. 8 for a model of these quantities)

    • In this model, the geometry can be arbitrary. However, disks and hemispheres are the most widely assumed geometries in the literature. On the other hand, our choice of a fcc lattice host is consistent with the bulk lattices of most of the metals studied experimentally at present
