The Fritz Haber Institute (FHI, in Berlin is one of the oldest and most renowned research institutes within the Max Planck Society (MPG), Germany's most successful scientific organization. At the FHI, researchers from all over the world are engaged in basic research in the fields of physics and chemistry at interfaces and surfaces, catalysis research, and molecular physics.

The Liquid-Vapor Interfaces group is offering a

Postdoctoral position (m/f/d)

Investigation of heterogeneous reactions at liquid-vapor interfaces

We are investigating fundamental interactions of ions, surfactants and trace gases at liquid-vapor interfaces, a topic with high relevance for atmospheric and environmental science. Our investigations are carried out using synchrotron-based liquid jet X-ray photoelectron spectroscopy at several synchrotron facilities in close collaboration with the Winter group at FHI. In addition we are using laboratory-based ambient pressure X-ray photoelectron spectroscopy at FHI, coupled with reflection-absorption infrared spectroscopy, and standard interface characterization methods such as surface tension. The results of these investigations provide insights into the molecular-scale structure of the liquid-vapor interfaces, which determines transport phenomena such as evaporation and gas adsorption, as well as controls the rate and mechanism of heterogeneous chemical reactions in the atmosphere.

Your tasks

The successful candidate further develops the laboratory-based ambient pressure XPS/IRRAS setup for liquid-vapor interface studies and carries out experiments on the interaction of trace gases with ions and surfactants at the interface of aqueous solutions with relevance to the atmosphere and environment. The lab-based investigations are accompanied by synchrotron beamtimes. You will also model the XPS data to arrive at a quantitative model of the interface chemical composition. Close collaboration with colleagues at FHI in the Theory department and the Winter group as well as staff at the synchrotrons is an integral part of the work.

    Your profile

    Applicants are expected to hold an excellent PhD degree in physics, chemistry, or a related fields. Experience in at least one of the areas of photoelectron spectroscopy or infrared spectroscopy is highly beneficial, in addition to familiarity with high vacuum instrumentation. We expect that the applicants are able to work in a highly collaborative environment.
