When a beam of electrons is fired at the surface of the material, these beams simulate several interactions. One of those interactions is Auger Electron Spectroscopy. The principle of Auger operates by allowing a high-energy electron from the beam to eject an electron from its orbit creating an empty hole in the orbit. As this occurs, another electron from a higher orbit moves to fill the empty space. As the electron changes from a higher to a lower orbit, it releases energy. This energy might eject a third electron from another orbit. By measuring the energy of the emitter electron, called the Auger electron, the atom can be identified. Different atoms have different atomic orbits and therefore different Auger energies.
Type: samples must be electro conductive
Size: There is no special sample preparation for auger spectroscopy
Precautions: samples must be clean and neat.
