In X-ray photoelectron spectroscopy, plot of the measured kinetic energy of a sharp Auger electron peak versus the binding energy of a photoelectron peak for the same element.
Notes: - Plots are usually made for a given element that can exist in different chemical states. Such plots are helpful in defining the state for an unknown sample, where measurements of the binding energy alone are inadequate.
- The binding energy is usually plotted on the abscissa, with values decreasing towards the right.
