LEED Auger Electron Spectroscopy
The Low Energy Electron Diffraction experiment uses a beam of electrons of a well-defined low energy (typically in the range 20 – 200 eV) incident normally on the sample. The sample itself must be a single crystal with a well-ordered surface structure in order to generate a back-scattered electron diffraction pattern.
