The Ernst Ruska-Centre (ER-C) for Microscopy and Spectroscopy with Electrons is a German research establishment conjointly operated by the Jülich Research Centre and RWTH Aachen University on a pari passu basis. The facility, which also offers user services to external research groups, is located on the campus of Research Centre Jülich belonging to the Helmholtz Association of German Research Centres. The Ernst Ruska-Centre (ER-C) for Microscopy and Spectroscopy with Electrons is a national user facility open to universities, research institutions and research laboratories in industry. Operational services of the ER-C are based on the guiding principle, that external users are accompanied by experienced scientists and technical support staff.
The scientific expertise provided by both institutions associated with the ER-C is of immense benefit to users seeking solutions to complex research problems. Staff scientists in Jülich are active on various different research fields: advanced analytical and high-resolution electron microscopy techniques are applied in the areas of electroceramics, oxide superconductors, spintronic materials, semiconductors and complex metallic alloys. The scientific research covers current issues in condensed matter physics, nanoelectronics and information technology and – as a matter of course – in the future development of sub-ångström and sub-electronvolt microscopy.
Besides offering general electron microscopy assistance to the solid state community, ER-C scientists also conduct their own research programmes. Current focal points include scrutinising both the theoretical and the applied aspects of high-resolution transmission electron microscopy, which represents the most important analysis methods at the centre. High resolution imaging is supplemented by electron holography and spectroscopy applications and microscopic in situ experiments.
Current in-house materials science research projects focus on the investigation of the epitaxial growth mechanisms and the relaxation behaviour of nanostructured material combinations using advanced software-based methods of transmission electron microscopy.
