dc.description.abstractEnElectron-phonon energy exchanges are investigated in 2D silver nanotriangles of thickness ranging from 5 to 8 nm and lateral size ranging from 25 to 85 nm, using time-resolved femtosecond spectroscopy in the low-perturbation regime. The measured electron-phonon decay time is smaller in 2D nanotriangles than in bulk silver, and its value corresponds to the decay time measured in isolated nanospheres with a diameter equal to the thickness of the nanotriangles. These results show that the electron-phonon energy exchanges in 2D nanosystems are strongly accelerated by confinement and this acceleration is directly governed by the smallest dimension of the nano-object.
