Helmholtz-Zentrum Potsdam Deutsches GeoForschungs­Zentrum (GFZ)

GFZ Potsdam

The Helmholtz-Zentrum Potsdam Deutsches GeoForschungsZentrum GFZ ( is the national research centre for Earth sciences of Germany.


The electron microscopy facility at the GFZ has been a focal point and driving force for earth sciences, physics and chemistry research in Germany for more than 20 years. The GFZ PISA facility provides earth science-specific, state-of-the-art electron microscopes that allow various workflows for structural, crystallographic and chemical imaging both in two- and three-dimensions. 

The GFZ EM facility hosts a FIB-SEM scanning electron microscope, equipped with both chemical and crystallographic detectors, which can be operated at the environmental pressure of 40 mbar; two transmission electron microscopes (TEM), both are equipped with analytical detectors, one has a probe corrector and the SuperX and GIF Continuum spectrometers. Moreover, the facility hosts a SEM equipped with cryogenic transfer system. Together, these instruments provide all necessities for the multi-scale analysis of earth materials. 


Nanoscale studies of earth materials: The facility has strong expertise in the preparation of micrometre-sized specimens via FIB-SEM nanomanipulation techniques. Through this, site-specific samples across areas of interest on earth material surfaces can be prepared for subsequent investigation within a TEM. We can also offer image and EDS Tomography.
Data Acquisition: Three-dimensional, nanoscale visualisation: GFZ has extensive knowledge in image acquisition, visualisation and interpretation for nanoscale-resolved, three-dimensional analysis of earth materials. These techniques encompass FIB-SEM and TEM-based tomography.
Crystallographic analysis of earth materials: GFZ offers a quantitative characterisation of earth materials employing EBSD from various geological environments.
