Plasmon-Induced Low Energy Interband Transitions in Porous Gold Films
We study ultrafast charge dynamics in porous gold films. Pump-probe experiments, supported by a semi-classical model, reveal transient plasmon-induced interband transitions below 2 eV, where these excitations are not observed in bulk gold.
