CaSTL Center Seminar with Charles Cherqui

Electron energy loss spectroscopy (EELS) in a scanning transmission electron microscope (STEM) has long been at the forefront of exploring the near-field behavior of localized surface plasmons (LSPs). However, in recent years the field has enjoyed a renaissance due to the increasing energetic and spatial resolution of state of the art STEMs. In this talk, I will review the history of EELS in the context of the plasmonics, the theoretical underpinnings of the experiment, and survey several significant results.  ​
