Theory of EELS in atomically thin metallic films
A. Rodríguez Echarri, Enok Johannes Haahr Skjølstrup, Thomas G. Pedersen +1
We study strongly confined plasmons in ultrathin gold and silver films by simulating electron energy-loss spectroscopy (EELS). Plasmon dispersion relations are directly retrieved f…

Quantum spill out in few-nanometer metal gaps: Effect on gap plasmons and reflectance from ultrasharp groove arrays
Enok J. H Skjølstrup, Thomas Søndergaard, Thomas G. Pedersen
Plasmons in ultranarrow metal gaps are highly sensitive to the electron density profile at the metal surfaces. Using a fully quantum mechanical approach, we study the effects of el…
