Introduction X-ray Photoelectron Spectroscopy (XPS). X-ray photoelectron spectroscopy works by irradiating a sample material with mono energetic soft x-rays causing electrons to be ejected. X-ray photoelectron spectroscopy (XPS or ESCA), is an analytical technique that depends upon the measurement of the energies of photoelectrons that are emitted from atoms when they are irradiated by soft X-ray photons (1 2 keV). X-ray photoelectron spectroscopy (XPS) is a surface-sensitive quantitative spectroscopic technique that measures the elemental composition at the parts per thousand range, empirical formula, chemical state and electronic state of the elements that exist within a material.
