Controlled in situ growth of tunable plasmonic self-assembled nanoparticle arrays
(2012)
Self-assembled silver nanoparticle (NP) arrays were produced by deposition at glancing angles on transparent stepped Al2O3 templates. The evolution of the plasmonic resonances has been monitored using reflection anisotropy ...
Reflectance anisotropy spectroscopy of magnetite (110) surfaces
(2014)
Reflectance anisotropy spectroscopy (RAS) has been used to measure the optical anisotropies of bulk and
thin-film Fe3O4(110) surfaces. The spectra indicate that small shifts in energy of the optical transitions, ...
In-situ characterisation of one-dimensional plasmonic Ag nanocluster arrays
(2011)
One-dimensional Ag nanoparticle arrays have been grown on step-bunched vicinal Al2O3 in ultrahigh vacuum using deposition at a glancing angle. The structures grown showed a strong optical anisotropy in the visible region ...
