While phonons and their related properties have been studied comprehensively in bulk materials, a thorough understanding of surface phonons for nanoscale objects remains elusive. Infra-red imaging methods with photons or electrons exist, which can map these vibrational excitations down to the individual atom scale. However, no technique so far was able to directly reveal the complete three-dimensional vectorial picture of the phononic electromagnetic density of states from a nanostructured…

Mapping vibrational surface and bulk modes in a single nanocube
By demonstrating the excitation of both bulk and surface vibrational modes using a single probe, this work represents advances in the detection and visualization of spatially confined surface and bulk phonons in nanostructures.
Position and momentum mapping of vibrations in graphene nanostructures
A new pathway is provided to determine phonon dispersions down to the scale of an individual free-standing graphene monolayer by mapping the distinct vibrational modes for a large momentum transfer.
Three-dimensional imaging of localized surface plasmon resonances of metal nanoparticles
3D images related to LSPRs of an individual silver nanocube can be reconstructed through the application of electron energy-loss spectrum imaging, mapping the excitation across a range of orientations, with a novel combination of non-negative matrix factorization, compressed sensing and electron tomography.
Nanoscale momentum-resolved vibrational spectroscopy
