The ER-C is a centre of excellence in advanced transmission electron microscopy and spectroscopy for addressing topical problems in solid state physics and chemistry, materials science, soft matter and biology.



The ER-C operates a user facility that provides access to state-of-the-art instruments, methods and expertise to universities, research institutions and industry. It is governed jointly by FZJ and RWTH Aachen.

Vincenzo Grillo, Alberto Roncaglia, Paulo Rosi and the Q-SORT project.


New techniques and instrumentation are developed by the ER-C’s scientific and technical staff in collaboration with academic and commercial partners, as well as with the instrumentation institutes in Forschungszentrum Jülich.



The ER-C is a key part of the European landscape of infrastructures for the characterization of materials using advanced techniques and instrumentation.

Lab tours of ER-C


The Ernst Ruska-Centre offers opportunities for students and scientists to conduct research in fundamental and applied electron microscopy. Students are given access to world-leading instruments and have the opportunity to work with experts in the field during the course of their Bachelor, Master or PhD thesis.

FeRAM: Polarisationsordnungen in Hafniumoxid

Towards the Further Miniaturization of FeRAM

Jülich / Aachen, 2 February 2021. Ferroelectric Random Access Memory, or FeRAM for short, offers both working memory and data storage in one. This saves on the time and energy needed by conventional computers to transport data between the two units. In addition, the saved data is retained even without a power supply. The write performance and service life of these components are already outstanding and the first FeRAMs are already in use, for example in chip cards or RFID tags. However, comparatively small amounts of data can as yet be stored on a FeRAM, as the space required for storing individual bits is too large. The latest studies using electron microscopes by scientists at Forschungszentrum Jülich and RWTH Aachen University now indicate a way to reduce the size of FeRAM bits by more than a factor of 100.


PICO 2021

The Sixth Conference on Frontiers of Aberration Corrected Electron Microscopy is scheduled to take place in spring 2021. Due to ongoing restrictions in connection with the Corona Pandemic, the format might be changed to an online conference. The conference will again address recent advances in methods and applications for the study of solids in condensed matter research and the life sciences by the application of advanced electron microscopy techniques.



ER-C for External Users

Access to the ER-C’s facilities is provided on the basis of peer-reviewed applications. Please contact our User Office for further information.


ER-C 2.0

As part of the programme to promote structural change in the Rhineland, the Ernst Ruska-Centre at Forschungs- zentrum Jülich is to be strategically expanded within the framework of the ER-C 2.0 project, and as a national research infrastructure for high-resolution electron microscopy, will create characterisation capabilities that are unparalleled world- wide. With its unique profile, the Rhineland is thus set to become Germany's most attractive region for the establishment of new materials technologies.


How the "PICO" Microscope Works

A unique transmission electron microscope with a resolution of 50 picometres has been available in the ER-C since February 2012. Learn here how the "PICO" (Advanced Picometre Resolution Project) works.



The Jülich Centre for Structural Biology ("JuStruct") is a user platform for determining atomically-resolved structures of medically and neurobiologically relevant proteins using NMR spectroscopy, X-ray crystallography, computer simulations, neutron scattering, neutron spectroscopy and cryo-EM.



ESTEEM3 – Enabling Science and Technology through European Electron Microscopy – is an EU funded project for electron microscopy, which aims at providing access to leading European state-of-the-art electron microscopy research infrastructures.



This European Research Council Synergy project aims at studying three-dimensional magnetic solitons with high temporal and spatial resolution, bringing together experts on magnetic imaging, magnetic manipulation, theory and device applications.



Thanks to smart phase manipulation, Q-SORT revolutionises the electron microscope by turning it into a so-called Quantum Sorter, yielding new insights in solid-state physics and biochemistry. This cutting-edge research project is funded by the EU’s FET OPEN Programme.
