X-Ray Photoelectron Spectroscopy
A quantitative spectroscopic technique that both determines the identities and percent composition of elements in a material and measures the elemental chemical and electronic states for a sample. The process, which occurs in a vacuum, involves the irradiation of the material of interest with a beam of aluminum or magnesium X-rays while measuring both the kinetic energy and number of electrons that are released from the outer surface.

Research Activity
Soft, mono-energetic x-rays illuminate a region of the sample and photoelectrons emanating from it are energy-analyzed. When coupled with an ion gun, depth profiling can be performed.
This technique provides elemental and chemical information about the surface region (first 1-30 monolayers) of nearly any solid material, is sensitive to all elements except hydrogen, and can provide some chemical information about the valence state of elements.
