Ernst Ruska-Centre for Microscopy and Spectroscopy with Electrons

Description The Ernst Ruska-Centre is one of the internationally leading centres for high-resolution microscopy and spectroscopy with electrons. In addition it is Germany's first national user centre for high-resolution transmission electron microscopy with a specific focus on aberration-corrected microscopy. The ER-C is jointly operated by the Jülich Research Centre and RWTH Aachen University and develops scientific infrastructure and advanced methods for present and future materials research. It contains an extensive range of state-of-the-art electron microscopes, including a newly-installed chromatic aberration corrected FEI Titan 50-300 G3 electron microscope referred to as the PICO instrument and an FEI Titan G2 60-300 instrument dedicated to electron holography and in situ electron microscopy. The ER-C hosts more than 25 staff who have expertise in the development of advanced methods in electron optics, quantitative image analysis and spectroscopy on the atomic scale, electron holography, electron tomography and in situ electron microscopy on solid state materials. Recent scientific activities include measurements of lattice distortions in crystalline solids with a precision of one picometre, measurements of lens aberrations and information limits in electron microscopes, simultaneous acquisition of HAADF images and monolayer resolved EELS signals, atomic-scale bright-field electron tomography using negative Cs imaging at low acceleration voltages, software development for computer-based retrieval of quantum-mechanical object wave functions from defocus series of images and high-precision analysis and correction of residual electron optical aberrations. The ER-C thus creates the necessary conditions for innovation on other branches of technology. In its own application related research programmes, the ER-C focuses on atomic scale phenomena of the solid state. This work provides a solid basis for developing new concepts in energy research as well as micro- and nanoelectronics.
