Energy-resolved hot carrier relaxation dynamics in monocrystalline plasmonic nanoantennas
Régis Méjard, Anthonin Verdy, Marlène Petit +3
Hot carriers are energetic photo-excited carriers driving a large range of chemico-physical mechanisms. At the nanoscale, an efficient generation of these carriers is facilitated b…
Plasmonic Purcell factor and coupling efficiency to surface plasmons. Implications for addressing and controlling optical nanosources
G. Colas des Francs, J. Barthes, A. Bouhelier +2
The Purcell factor is a key quantity in cavity quantum electrodynamics (cQED) that quantifies the coupling rate between a dipolar emitter and a cavity mode. Its simple form $…
Excitation of plasmonic nanoantennas with nonresonant and resonant electron tunnelling
Alexander V. Uskov, Jacob B. Khurgin, Igor E. Protsenko +2
A rigorous theory of photon emission accompanied inelastic tunnelling inside the gap of plasmonic nanoantennas has been developed. The disappointingly low efficiency of the electri…
Dynamics, effciency and energy distribution of nonlinear plasmon-assisted generation of hot carriers
O. Demichel, M. Petit, S. Viarbitskaya +6
We employ nonlinear autocorrelation measurements to investigate plasmon-assisted hot carrier dynamics generated in optical gold antennas. We demonstrate that surface plasmons enabl…
