Influence of surface roughness on the optical properties of plasmonic nanoparticles
Andreas Truegler, Jean-Claude Tinguely, Joachim R. Krenn +2
For plasmonic nanoparticles, we investigate the influence of surface roughness inherent to top-down fabrication on the optical properties, and find that it has a surprisingly small…
Analysis of damping-induced phase flips of plasmonic nanowire modes
Andreas Hohenau, Primoz Kusar, Christian Gruber +1
We launch surface plasmons from one end of a silver nanowire by asymmetric illumination with white light and use plasmon-to-light scattering at the nanowire ends to probe spectrosc…
Plasmonic modes of gold nano-particle arrays on thin gold films
Andreas Hohenau, Joachim R. Krenn
Regular arrays of metal nanoparticles on metal films have tuneable optical resonances that can be applied for surface enhanced Raman scattering or biosensing. With the aim of devel…
