The energies and intensities of the photoelectron peaks enable identification and quantification of all surface elements (except hydrogen).Īs the demand for high performance materials increases, so does the importance of surface engineering. Peaks appear in the spectrum from atoms emitting electrons of a particular characteristic energy. A photoelectron spectrum is recorded by counting ejected electrons over a range of electron kinetic energies. XPS spectra are obtained by irradiating a solid surface with a beam of X-rays while simultaneously measuring the kinetic energy and electrons that are emitted from the top 1-10 nm of the material being analyzed. XPS can measure the elemental composition, empirical formula, chemical state and electronic state of the elements within a material. ![]() X-ray photoelectron spectroscopy (XPS) is a technique for analyzing the surface chemistry of a material.
