Project DescriptionSize-dependent structural and electronic effects make sub-nm clusters extremely interesting for highly selective, mild, sustainable catalysis. We investigate model catalysts of clusters, produced with atomic size selection, in reactive gas environments using a sophisticated near-ambient pressure scanning tunneling microscope (NAP-STM). By recording videos, we can follow catalyst restructuring in situ upon heating, due to adsorbates, or during a reaction, obtaining unique insight into the elusive dynamics of a working catalysts. X-ray photoelectron spectroscopy (NAP-XPS) complements microscopy with information on the chemical composition and oxidation state of the system. These measurements are performed both at synchrotrons and with our on-site lab-based instrument.As the successful candidate, you will prepare the samples, perform and analyze NAP-STM experiments and maintain the UHV apparatus. In addition, you will occasionally perform NAP-XPS experiments, both at synchrotrons (e.g. Lund, Barcelona, Berkeley) and on-site using a new lab-based system. You will benefit from membership at the TUM Graduate School and an active international scientific network within the Cluster of Excellence e-conversion and a DFG Collaborative Research Center. You will participate in meetings with international collaborators, present your results at national and international conferences, and write publications for internationally renowned journals.

Please send your CV, letter of motivation (max. 1 page) and two letters of reference to Prof. Dr. Barbara A. J. Lechner (recruitment.lechner@tum.de). Only complete applications will receive full consideration. The position is open until 30/04/2024 or until filled.
