Technology Description:

The Flextrua cluster growth tool at the Micro and Nanotechnology Laboratory at the University of Oslo (UiO MiNaLab) is connected to an analysis chamber for advanced sample characterization. A plethora of concomitant surface science techniques are available that utilise a variety of photon sources, a state-of-the-art hemispherical electron analyser and low energy electron diffraction optics. The XPS system can resolve the chemical composition (stoichiometry) and elemental chemical environment.
