Abstract Details: Plasmonic nanostructures can be used as canonical building blocks to host and actively participate in a variety of complex physical phenomena such as non-linear effects, quantum tunneling or photoemission, to cite a few. We will present a number of examples where a conductive contact between the two arms of a gap-antenna is used for (i) effective control of the near-field oscillations in the loaded antenna [1], (ii) relating transport and optical properties based on the evolution of the Plasmon excitations [2], and (iii) producing optical spectral switch based on the presence of a photoconductive material linking the gap that can sustain a fast and large free-carrier density [3].
