Progress in electron-beam spectroscopies has recently enabled the study of optical
excitations with combined space, energy and time resolution in the nanometre …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Hybrid nanostructures composed of graphene or other two-dimensional (2D) nanomaterials
and plasmonic metal components have been extensively studied. The unusual properties of …

Free electron beams such as those employed in electron microscopes have evolved into
powerful tools to investigate photonic nanostructures with an unrivaled combination of …

Here, we review the progress and most recent advances in phonon-polaritonics, an
emerging and growing field that has brought about a range of powerful possibilities for mid …

Coupling noble metal nanoparticles by a 1 nm gap to an underlying gold mirror confines
light to extremely small volumes, useful for sensing on the nanoscale. Individually …

Surface-enhanced Raman scattering (SERS) spectroscopy is one of a few techniques that
are capable of ultimately detecting matter at single molecule scale.[1] As a powerful analysis …

That a nanoparticle (NP)(for example of gold) residing above a gold mirror is almost as
effective a surface enhanced Raman scattering (SERS) substrate (when illuminated with …

Electron energy loss spectroscopy (EELS) performed in a scanning transmission electron
microscope (STEM) has demonstrated unprecedented power in the characterization of …

Graphene is used as the thinnest possible spacer between gold nanoparticles and a gold
substrate. This creates a robust, repeatable, and stable subnanometer gap for massive …
