Optical absorption of silicon nanowires
Tao Xu, Yannick Lambert, Christophe Krzeminski +6
We report on simulations and measurements of the optical absorption of silicon nanowires (NWs) versus their diameter. We first address the simulation of the optical absorption base…
Phonons in Slow Motion: Dispersion Relations in Ultra-Thin Si Membranes
John Cuffe, Emigdio Chavez, Andrey Shchepetov +11
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…
Bound States of Defects in Superconducting LiFeAs Studied by Scanning Tunneling Spectroscopy
S. Grothe, Shun Chi, P. Dosanjh +5
Defects in LiFeAs are studied by scanning tunneling microscopy (STM) and spectroscopy (STS). Topographic images of the five predominant defects allow the identification of their po…
