XPS (X-Ray Photoelectron Spectroscopy)

XPS X-ray Photoelectron Spectroscopy involves directing X-rays of controlled energy onto the surface of a material. The interaction of these X-rays with the constituent atoms of the material’s outermost layers (effective penetration of between 2 and 10 nm) provides sufficient energy to eject electrons from the various atoms. These electrons leave the atoms with a characteristic kinetic energy that provides information on the type of atom (element) to which they belong and the types of atoms (elements) that may be interacting with the atom from which the electron originates.
