Tailored Hypersound Generation in Single Plasmonic Nanoantennas

Mostrar todas las versiones(2)

Ultrashort laser pulses impinging on a plasmonic nanostructure trigger a highly dynamic scenario in the interplay of electronic relaxation with lattice vibrations, which can be experimentally probed via the generation of coherent phonons. In this Letter, we present studies of hypersound generation i...
