X-ray photoelectron spectroscopy (XPS)
X-ray photoelectron spectroscopy (XPS) is a powerful analytical technique used to study the surface chemistry of materials. It works by shining X-rays onto a sample, which causes electrons to be ejected from the surface. By measuring the energy of these electrons, scientists can determine the elemental composition and chemical state of the materials present. XPS is particularly valuable in fields like materials science and electronics, as it provides detailed information about thin films, coatings, and surface interactions, helping researchers understand the properties and behaviors of different substances at the atomic level.
