X-ray photoelectron spectroscopy enables XPS surface analysis, providing elemental composition and the chemical/electronic state of the top 10 nm of a material.
What is X-ray photoelectron spectroscopy (XPS)? XPS can measure the elemental composition, empirical formula, chemical state, and electronic state of the elements within a material. XPS spectra are obtained by irradiating a solid surface with a beam of X-rays while simultaneously measuring the kin...
