Light Emission in Nanogap Emitting Devices: efficiency issues
Résumé
In this contribution, we clarify through analytical derivations in the limit of small gap thickness why in nanogap antennas, quenching is not necessarily dominant at small gap thickness, why quantum emitters may offer good efficiencies, what are the circumstances in which high efficiency is obtained, and whether there existsan upper bound for the maximum efficiency achievable in nanogap antennas.
