This apparatus is equipped with an STM in a UHV chamber with XPS, ISS, and QMS for TPD. Besides these basic surface science methods the chamber also has the possibility for heat treatment, gas exposure, and in situ metal deposition.
The equipment is used for studies of surface structures and surface alloying on single crystals. After preparation and characterization, the samples can be transferred out of the chamber through a load lock system for further investigations e.g. in the electrochemistry laboratory. This facilitates direct comparison between well-characterized structural properties and catalytic performance.
