Metallic conduction in atomic-scale highly P-doped Si nanowires is theoretically studied using a tight-binding approach coupled to Schrodinger-Poisson simulations. The density of states and spatial distributions of electrons confirm they remain metallic down to the atomic-scale, which bodes well for their utility as ultra-thin metallic interconnects for atomic-scale devices.
