Optical and electrical probing of plasmonic metal-molecule interactions
Andrei Stefancu, Wenxuan Tang, Ming Fu +9
Plasmonic nanostructures enable efficient light-to-energy conversion by concentrating optical energy into nanoscale volumes. A key mechanism in this process is chemical interface d…
Semiconductor Metasurfaces for Surface-enhanced Raman Scattering
Haiyang Hu, Anil Kumar Pal, Alexander Berestennikov +5
Semiconductor-based surface-enhanced Raman spectroscopy (SERS) substrates, as a new frontier in the field of SERS, are hindered by their poor electromagnetic field confinement, and…
Advances in ultrafast plasmonics
Alemayehu Nana Koya, Marco Romanelli, Joel Kuttruff +22
In the past twenty years, we have reached a broad understanding of many light-driven phenomena in nanoscale systems. The temporal dynamics of the excited states are instead quite c…
Fermi level equilibration at the metal-molecule interface in plasmonic systems
Andrei Stefancu, Seunghoon Lee, Li Zhu +4
We highlight a new metal-molecule charge transfer process by tuning the Fermi energy of plasmonic silver nanoparticles (AgNPs) in-situ. The strong adsorption of halide ions upshift…
