The TEM Center of the Faculty of Engineering at the Christian-Albrechts-University in Kiel provides the opportunity to study the chemical, morphological and structural properties of micro and nanomaterials at three Transmission Electron Microscopes (TEM), a scanning electron microscope (SEM), and an X-ray diffractometer (XRD). TEM techniques include high-resolution electron diffraction (HRTEM), high-resolution electron diffraction (SAED), energy-dispersive X-ray spectroscopy (EDX), electron energy loss spectroscopy (EELS), Lorentz microscopy (LTEM), tomography, and in situ methods (heating, cooling, and biasing). Additionally to the microscopy itself, various possibilities for sophisticated preparation of samples are available. The scientific director of the TEM Center is at the same time the leader of the group “Synthesis and Real Structures”, at the moment Prof. Dr. Lorenz Kienle. A TEM coordinator is responsible for the organization of the current projects including accounting. One scientist oversees the XRD and SEM. A technician is in charge of the preparation laboratories. A controlled and transparent access is assured for all scientists at the university.
