XPS is based on the photoelectric effect, where a material surface is irradiated with a focused X-ray beam, causing atoms to emit photoelectrons. By measuring the kinetic energy and intensity of these emitted electrons, XPS can identify the elements present on the surface and analyze their chemical bonding environments. Because photoelectrons can only escape from a very shallow region of the material, typically within a few nanometers, XPS provides highly surface-sensitive analysis.
