The ER-C is one of the word-wide leading institutes for high-resolution electron microscopy and has a long-standing tradition in the development of methods for high-resolution electron microscopy. Under the former direction of Professor Knut W. Urban, aberration correction for electron optics was co-developed here in the 1990s and the very first prototype of an aberration-corrected TEM was installed.

Today, ER-C scientists are active in various research fields:

  • Method development in advanced analytical and high-resolution electron microscopy and the future development of sub-ångström and sub-electronvolt microscopy.
  • Materials science and high-resolution characterisation in various areas such as electroceramics, oxide superconductors, spintronic materials, semiconductors, complex metallic alloys and catalysts. 
  • The Structural Biology department (ER-C-3) uses cryo-electron microscopy as the central method to investigate the structural biology of fundamental cellular processes.

The ER-C currently operates six aberration-corrected high-resolution (scanning-) transmission electron microscopes and a large number of additional electron microscopes. Additional equipment for microstructural characterization, advanced in-situ experiments and sample preparation is also available. Find out more on this website.
