Mangir Murshed about the LabRam ARAMIS:
“Using the microfocus Raman spectroscopy, I analyze the fingerprints of molecules and crystals, revealing their chemical composition and structural details.”
© Patrick Pollmeier, Universität Bremen
Marcos Toro about the coupled Raman-VSI Spectrometer:
"Coupling two optical methods for the analysis of surfaces allows us to study the molecular composition and the topological features of a surface in one instrument."

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

mehr

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.

mehr

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

mehr

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