Physical and Theoretical Chemistry

Prof. Günther (b. 1962) conducts research into surface science and heterogeneous catalysis. He uses models to image catalytic reactions and processes at interfaces. Microscopy and spectroscopic techniques are combined, with particular use made of scanning tunneling microscopy, photoelectron (spectro) microscopy and low energy electron microscopy (LEEM). With respect to heterogeneous catalysis, the aim is to enable elevated pressure conditions for the models using an ultra-high vacuum.
