Transmission Electron Microscopy

Electron energy loss spectroscopy (EELS) is the analysis of the distribution of electron energies emergent from a thin-foil specimen. The electrons in the primary beam are decelerated and lose energy as they pass through the thin sample by several mechanisms, but it is the loss due to ionization of inner shell electrons in the sample that provides the most useful information.
