Title :
Fully Atomistic Simulations of Phonon-Limited Mobility of Electrons and Holes in
-,
 with 〈001〉, 〈110〉, and 〈111〉 orientations are calculated in a fully atomistic framework for diameters up to 10 nm. Electron-phonon scattering rates are computed with an <i>sp</i><sup>3</sup><i>d</i><sup>5</sup><i>s*</i> tight-binding model for electrons and a valence-force field model for phonons. The Boltzmann equation is then solved exactly for the low-field mobility. Compared to bulk Si, the electron mobilities are strongly reduced, but the hole mobilities can be enhanced in 〈111〉 and 〈110〉 NWs with diameters around 3.5 nm. The mobility, however, rapidly decreases with carrier concentration >; 10<sup>19</sup> cm<sup>-3</sup>.</div>
