Plasmonic with electrons
In collaboration projects, we use various electron spectroscopy methods to probe the plasmonic properties of nanostructures.
In cooperation with the Graz University of Technology, we exploit the high spatial resolution of electron-microscopy-based electron energy loss spectroscopy and cathodoluminescence to analyze in detail plasmon field profiles and dispersions [1,2,3]. On the other hand, photoelectrons emitted from metal nanoparticles and accelerated in their plasmon fields are valuable probes of plasmons, as we investigate together with the Wigner Institute, Budapest and the Graz University of Technology [4,5].
