Photoemission Spectroscopy (XPS&UPS) Facility

Available techniques

  • Elemental composition
  • Detection of contaminants
  • Quantitative analysis
  • Determination of chemical or electronic state of each element on the surface
  • Layer ordering in the first 8-10 nm (relative depth plot)
  • Work function, ionization energy and valence band measurement using UPS
  • Direct band mapping using ARUPS
  • Temperature-dependent XPS measurements
  • In-situ preparation of materials by thermal evaporation for later analysis
