Physics of Nanoscale Systems (ER-C-1) / Microstructure Research (PGI-5)

Development of new procedures for understanding material properties on the atomic level with a special focus on ultrahigh resolution electron microscopy techniques. In the near future, the life sciences will be added as the first new field of application. Furthermore, we enable researchers from science and industry to use our instruments and methods, supported by our experts, and aim to establish a national user facility for the scientific community.

Aberration Correction

Aberration Correction

The first spherical-aberration(Cs) corrected TEM was co-developed and operated at the ER-C. Today this technique defines state-of-the-art electron microscopy and has been commercialized in more than 1000 instruments worldwide. 

Catalysis

Nanomaterials for Green Energy

The properties of new materials for energy conversion and storage are very often linked to their atomic-scale structure. One example are novel fuel cell catalysts. High-resolution analytical in-situ electron microscopy helps us to understand such materials under realistic working conditions.

Electroceramics and nanoelectronic oxides

Electroceramics and nanoelectronic oxides

By employing the negative Cs imaging technique (NCSI) on our PICO electron microscope light elements like oxygen are resolved with high contrast in the heavy element environment. Like this, the improvement of spatial resolution resulted from the Cs/Cc correction can directly be demonstrated by the visibility of 57 pm separation of Y-Y atom columns projected along the [010] axis of a Ce doped YAP single crystal.

Magnetism

Magnetism on the 
nanoscale

Magnetic materials are essential for data recording and storage, energy conversion and biomedical technologies. We apply and develop high-resolution quantitative methods to measure the magnetic properties of nanostructures and magnetic phenomena (e.g. domain walls, skyrmions) using various electron microscopy methods.

Skyrmion Research: Braids of Nanovortices Discovered

A team of scientists from Germany, Sweden and China has discovered a new physical phenomenon: complex braided structures made of tiny magnetic vortices known as skyrmions. Skyrmions could provide a possible basis for innovative concepts in information processing that offer better performance and lower energy consumption.

PGI Colloquium - Hybrid event: Prof. Dr. Alexander Gray,
Temple University, Philadelphia, USA

Emergent phenomena at complex-oxide interfaces have become a vibrant field of study in the past two decades due to the rich physics and a wide range of possibilities for creating new states of matter and novel functionalities for potential devices. Electronic-structural characterization of such phenomena presents a unique challenge due to the lack of direct yet non-destructive techniques for probing buried layers and interfaces with the required Ångstrom-level resolution, as well as element and orbital specificity.
