MAPEX Core Facility for Materials Analytics

More than a tool box:

We work together to push materials analytics beyond the state of the art in five investigation areas, coupling experimental characterization with materials modelling and simulation.

3D Materials Analytics

We use X-rays to non-destructively inspect the three-dimensional distribution of matter inside the object of investigation.

XRM picture

Electron Microscopy

We investigate our samples using high-energy electron beams to obtain images with resolution down to the atom scale.

Momentum resolved STEM

Surface Analytics

We combine microscopic and spectroscopic techniques to monitor processes at materials surfaces.

vertical Scanning Imaging and superimposed Raman Shift


We perform in-situ and real-time chemical, electronic and optical characterization of materials under different conditions, e.g. to identify and map different phases.

Spectroscopy picture

X-ray Diffraction

We support structure investigations of materials from crystalline nanomaterials to macroscopic single crystals at ambient and non-ambient conditions.

X-Ray Diffraction

Materials Modeling

We develop and apply computational methods from quantum mechanics to continuum theories to design and understand new materials and processes.
