Data supporting "Interrogating Nanojunctions Using Ultraconfined Acoustoplasmonic Coupling". Abstract: Single nanoparticles are shownto develop a localized acoustic resonance, the bouncing mode, when placed on a substrate. If both substrate and nanoparticle are gold, plasmonic coupling of the nanoparticle to its image charges in the film induces tight light confinement in the nanogap. This yields ultrastrong “acousto-plasmonic” coupling with a figure of merit 7 orders of magnitude higher than conventional acousto-optic modulators. The plasmons thus act as a local vibrational probe of the contact geometry. A simple analytical mechanical model is found to describe the bouncing mode in terms of the nanoscale structure, allowing transient pump-probe spectroscopy to directly measure the contact area for individual nanoparticles. The data is for the figures contained in the paper Interrogating Nanojunctions Using Ultraconfined Acoustoplasmonic Coupling.
