We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \sim 8 nm. We observe a reduction of the phase and group velocities of the fundamental flexural mode by more than one order of magnitude compared to bulk values. The...

Fully atomistic simulations of phonon-limited mobility of electrons and holes in <001>-, <110>-, and <111>-oriented Si nanowires

Y.M. Niquet, C. Delerue, D. Rideau, Brice Videau

Phonon-limited mobilities of electrons and holes in Si nanowires (NWs) 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 sp3d5s* tight-binding model for electrons and a valence-...
