When performed in a scanning transmission electron microscope, EELS can simultaneously render images of nanoscale objects with subnanometer spatial resolution and correlate them with spectroscopic information at a spectral resolution of ∼10–100 meV. This scattered incident electron is detected in the spectrometer and gives rise to the electron energy loss signal. Electron energy-loss spectroscopy (EELS) involves analyzing the energy distribution of initially monoenergetic electrons, after they have interacted with a specimen. However, options for in situ chemical identification are limited: X-ray analysis is precluded because the liquid cell holder shadows the detector and electron energy-loss spectroscopy (EELS) is degraded by multiple scattering events in thick layers.
