Abstract
The authors provide a theoretical analysis of the influence of confinement on the hole-optical phonon interaction in freestanding Si nanowires. Their model based on deformation potential optical phonons shows that in narrow quantum wires, hole scattering is less frequent than when calculated with a bulk (continuous) phonon spectrum. In addition, scattering by confined optical phonons results in dissimilar rates for backward and forward events, in contrast with continuous phonons.
