Fernandes, Benoît Dacosta Beulze, Aurélie Le Moroté, Fabien Oberlé, Jean Tréguer-Delapierre, Mona Burgin, Julien Langot, Pierre Electron–Phonon Scattering in 2D Silver Nanotriangles Electron–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. 85 nm;8 nm;2 D nanotriangles;results show;decay time;thickness;2 D silver nanotriangles;bulk silver;2 D nanosystems;electron 2013-10-24
