Hot Electrons Remote Excitation and their Ultrafast Dynamics

Hot electron-based devices are quite promissing for ultrafast photodetection and to set off enhanced physicochemical reactions [1] . Controlling their generation at the nanoscale within plasmonic devices is a key for the future development of hybrid hot-electrons technologies. Indeed, Surface Plasmon-Polaritons (SPPs) can be exploited to confine light and enhance the number of excited hot carriers [2] . We aim at studying the excitation and dynamics of hot electrons, enhanced by plasmonics, with two different approaches.
