Research Group Gerthsen - Laboratory for Electron Microscopy (LEM)

Electron microscopy, electron optics, materials science
Research Group Gerthsen

The Laboratory for Electron Microscopy (LEM) is a core facility of the Karlsruhe Institute of Technology (KIT). The LEM focuses on the application of electron microscopic and electron spectroscopic methods to study samples from numerous KIT groups. The LEM conducts transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM) and scanning electron microscopy (SEM) due to the broad range of analysis tasks. These techniques are combined with energy dispersive X-ray spectroscopy (EDXS) and electron energy loss spectroscopy (EELS) to analyze chemical composition and electronic properties on the nanoscale. Nanostructuring is performed with two focused-ion-beam systems (FIB-SEM). Further available techniques include electron tomography, electron holography and backscatter electron diffraction (EBSD). In addition to service electron microscopy, LEM is involved in research projects in the fields of materials science, solid state physics and chemistry in cooperation with other groups. Our research also aims at methodological developments. Another focus is the development of electron-optical aberration correctors.We regularly offer electron-microscopy and electron-optics lecture courses as well as lab exercises to train students and young scientists.
