Institute of Solid State Physics, Section Electron Microscopy (IFP-Elektronenmikroskopie)
The working group Electron Microscopy at the Institute for Solid State Physics is engaged in the development of quantitative
electron microscopy methods. Currently, the group consists of 10 staff members who have high expertise in the field of electron
microscopy and materials science. As part of the Institute of Solid State Physics, the focus lies in the analysis of nanostructures
such as nanowires, semiconductor heterostructures, semiconducting oxide materials, nanoporous gold and metallic nanoparticles.
Besides several instruments for sample preparation, the working group is provided with an FEI Nova 200 Nanolab dual beam system.
The FEI Titan 80-300 transmission electron microscope (TEM) with aberration corrector for the objective lens installed in
2008 allows analyses in the subnanometer or subangström scale. The Titan microscope is equipped with a Si (Li) EDX detector
and an energy filter. In 2021, the working group was provided with a Thermo-Fisher SPECTRA 300 TEM with probe corrector. This
microscope is equipped with a monochromator, a Super-X EDX detector, a pixel array detector (EMPAD) with an acquisition rate
of 1000 images per second and several tomography specimen holders. The electron microscopes of the working group are integrated
into the "MAPEX Center for Materials and Processes” Core Facility.

Scientific Services
As a longtime cooperation partner of scientific and industrial research and development groups the working group Electron
Microscopy provides external users with a pool of different electron microscopy analysis techniques. The provided services
range from specimen preparation over planning and realization of experiments to data analysis and survey of results. While
the measurements at the microscopes are usually performed by working group staff, external users can perform specimen preparation
and data analysis self-directed after a short introduction. However, a full specimen characterization by an employee of the
working group is also possible. This includes specimen preparation, data acquisition/analysis and a compilation of results.
Depending on the scientific problem a SEM/FIB system (FEI Nova 200 Nanolab) and two TEMs (Thermo-Fisher Spectra 300, Titan
80/300) are available for experiments. While the Spectra 300 with its probe-corrector and monochromator is well suited for
STEM applications, the Titan 80/300 allows the acquisition of aberration-corrected TEM images. Both TEMs are also equipped
with a variety of detectors that allow for spectroscopic analysis such as EDX or EELS.
