[8a-Z09-6] Influence of pnonon-boundary scattering on phonon-drag effect in Si wires
Keywords:Seebeck coefficient, phonon drag effect, Si wire
We have analyzed the relationship between phonon-drag effect of Seebeck coefficient and wire sizes in Si wires from a viewpoint of specularity in phonon boundary scattering. As a result, even in Si nanowires, the phonon-drag effect can be preserved by making the wire surfaces ultmately flat.
