Beschreibung

We are currently looking for a PhD student for the Spectro-Microscopy group () at the Department of Interface Science.

1 PhD student position (M/F/d)

Project:
Spectromicroscopy Studies of Complex Processes in Thermal Catalysis

The group operates an ultra-high vacuum (UHV) based aberrations corrected and energy filtered Low Energy and Photoemission Electron Microscopy (LEEM/PEEM) at the UE49PGM-SMART high flux soft x-ray beamline at BESSY-II.

This spectromicroscope is used to characterize catalytically active surfaces such as single crystal surfaces, oxide films and supported nanoparticles (NP) and to follow in real time and in situ processes such as epitaxial film growth, thermal reactions in a pressure range up to 10-5 mbar and phase transitions.

Various special equipment are connected to the microscope allowing for quasi in situ processes like UHV based plasma treatment, chemical reactions in near ambient pressure (NAP) and electrochemistry.

The instrument excels at (1) the comprehensive characterization by combing various microscopy, diffraction and spectroscopy tools at high lateral and energy resolution of up to 2.6 nm and 180 meV, respectively, (2) high and tunable surface sensitivity between 0.3 and 3 nm, (3) high chemical sensitivity (elemental composition, chemical state) and structural sensitivity (surface reconstruction of absorbed species, crystallinity, surface facet orientation) and (4) fast acquisition of the full field image (higher than video rate).

Furthermore, the group operates a pure LEEM/PEEM microscope which is equipped with a high-pressure cell (HPC) to quasi in situ study chemical reactions on catalytically active surfaces with reactive gases in a pressure range up to 20 bar.

The third instrument is an unique NAP-LEEM/XPEEM which is dedicated to observe in real time thermal reactions in the mbar range.

Requirements:

A strong master degree in Chemistry, Physics or Physical Chemistry, preferably with a specialization in thermal catalysis or surface science.
Knowledge about surface science techniques like e.g. XPS, NEXAFS, LEED, PEEM, LEEM, TDS.
Experience at performing complex UHV experiments with a high drive to solve scientific and practical/instrumental challenges independently.
Experience working at synchrotron light sources (preferred, but not required)
Ability to work in a team.
Collaborative spirit and excellent English skills.

Berlin

The Fritz Haber Institute (FHI) is located in the quiet south-west of Gemany's capital Berlin, which is a large, tolerant and cosmopolitan city.

Berlin offers a wide variety of culture, art, music, and outdoor opportunities.

The BESSY-II synchrotron light source of the HZB is one of the worldwide leading soft x-ray light source and is located in the south-east of Berlin.

The Fritz Haber Institute is a cooperative research partner and operates a few beamlines and endstations at BESSY.
