Photoemission spectroscopy

Wikipedia Overview

Photoemission spectroscopy (PES), also known as photoelectron spectroscopy, refers to energy or spin measurement of electrons emitted from solids, gases or liquids by the photoelectric effect, in order to determine the binding energies or magnetic properties of electrons in the substance. The term refers to various techniques, depending on whether the ionization energy is provided by X-ray, EUV or UV photons. Regardless of the incident photon beam, however, all photoelectron spectroscopy revolves around the general theme of surface analysis by measuring the ejected electrons.
