Photoemission Spectroscopy (XPS&UPS) Facility
The ICN2 Photoemission Spectroscopy Facility is equipped with a state-of-the-art XPS and UPS system (SPECS PHOIBOS 150 hemispherical energy analyser) for the electronic and chemical characterisation of the surface of a wide range of materials.
It provides services to both internal and external users for routine XPS analysis, as well as supporting long-term experiments requiring in-situ preparation and modification.
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, ionisation 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
