Surface-Sensitive Raman Scattering by Transferable Nanoporous Plasmonic Membranes
Roman M. Wyss, Günter Kewes, Martin Frimmer +11
Raman spectroscopy is a powerful technique to characterize materials. It probes non-destructively chemical composition, crystallinity, defects, strain and coupling phenomena. Howev…
Freestanding and permeable nanoporous gold membranes for surface-enhanced Raman scattering
Roman M. Wyss, Markus Parzefall, Cynthia M. Gruber +6
Surface-enhanced Raman spectroscopy (SERS) demands reliable, high enhancement substrates in order to be used in different fields of application. Here, we introduce freestanding por…
Understanding the interaction between energetic ions and freestanding graphene towards practical 2D perforation
Jakob Buchheim, Roman M. Wyss, Ivan Shorubalko +1
We report experimentally and theoretically the behavior of freestanding graphene subject to bombardment of energetic ions, investigating the ability of large-scale patterning of fr…
