We analyze the effect of low dimensionality on the electrical conductivity (σ) and Seebeck coefficient (S) in ultra-narrow Si nanowires (NWs) by employing atomistic considerations for the electronic structures and linearized Boltzmann transport theory. We show that changes in the geometrical features of the NWs such as diameter and orientation mostly affect σ and S in two ways: (i) the distance of the band edges from the Fermi level (ηF) changes, and (ii) quantum confinement in some cases…
