High resolution scans of each of the element peaks of interest can be obtained to give more information about the material. Copyright: American Chemical Society (2006). Electrons emitted have characteristic kinetic energies proportional to the energy of the radiation, according to \ref\) High resolution S2p (left) and Na1s (right) XP spectra of phenyl sulfonated SWNTs. The photoelectric effect is the ejection of electrons from the surface of a material upon exposure to electromagnetic radiation of sufficient energy. It can be further applied to determine the chemical or electronic state of these elements. X-ray photoelectron spectroscopy (XPS), also called electron spectroscopy for chemical analysis (ESCA), is a method used to determine the elemental composition of a material’s surface. ![]()
