Displacement field of the phonon modes for 1.6-nm-thick Si square nanowire
26 Sep 2014 | Contributor(s):: Igor Bejenari
The phonon modes of 1.6-nm-thick Si square nanowires with [100] crystalline orientation are shown. The [010] and [001] facets are passivated by hydrogen and there are Si-Si dimers on the nanowire surface. The phonon dispersion and eigenvectors were calculated from a valence force field model of...
