Two-Photon Photoelectron Spectroscopy Analyzer(ISUPAM)

    Photoelectron spectroscopy uses the principle of photoelectric effect to extract the kinetic energy of photoelectrons from the sample(and thereby determine its binding energy)and angular distribution, and apply this information to study atoms, molecules, condensed phases, especially solids. The electronic structure of the surface. Photoelectron spectroscopy is a surface sensitive technique. The mean free path of photoelectron inelastic scattering in solids is usually 1.5~3.0nm, so photoelectrons reflect the information of solid surface.
