Generation and detection of surface acoustic waves using single plasmonic nanoresonators

Mostrar todas las versiones(2)

We show in this work that coherent phonons generated after the decay of optically-excited plasmons in isolated metallic nanoantennas, are transmitted through the substrate as surface acoustic waves (SAWs) which can be detected by other nanoantennas used as receptors and positioned at distances up to...
