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…
Magnetic relaxation of exchange biased (Pt/Co) multilayers studied by time-resolved Kerr microscopy
Fabien Romanens, Stefania Pizzini, Fabiano Yokaichiya +8
Magnetization relaxation of exchange biased (Pt/Co)5/Pt/IrMn multilayers with perpendicular anisotropy was investigated by time-resolved Kerr microscopy. Magnetization reversal occ…
