Laboratory for Astrochemistry and Reactions on Surfaces

Surface Science and Surface Reactions

In the Laboratory for Astrochemistry and reactions on surfaces, INTERCAT research will be performed with 5 ultra-high vacuum experimental end stations. These complex experimental systems are designed for surface science research and combine cryo-techniques - down to 4 K, scanning tunnelling microscopy, temperature programmed desoprtion and x-ray photoelectron spectroscopy.  

The Laboratory for Astrochemistry and Reactions on Surfaces at the Department of Physics & Astronomy is home to the experimental research activities of InterCat. The laboratory was founded in 2007 and consists of a laboratory in the basement of the Department of Physics & Astronomy and a second in the Interdisciplinary Nanoscience Center (iNANO).
