Transmission Electron Microscopy
These are the methods and techniques offered at the TEM Center Kiel
- High resolution imaging (HRTEM) is frequently used to analyze real structures to determine the atomic structure of interfaces, defects, domains, modulations and other traces of structural complexity.
- Lorentz microscopy (LTEM) allows observing magnetic domains statically as well as dynamically by changing the magnetic field at the sample position.
- Selected area Diffraction (SAD) and precession electron diffraction (PED) are methods using electron diffraction to create an image. Therefore these images contain information like the lattice constant of the sample. PED even enables to solve and refine unknown structures ab-initio.
- Energy dispersive X-ray (EDX), Electron Energy Loss Spectroscopy (EELS) and Energy filtering TEM (EFTEM) are used to obtain information about the chemical composition of the sample. In the scanning mode of the TEM variations of the stoichiometry with high energy- and lateral resolution can be detected.
- Tomography is applied to create a 3D image of the sample, e.g. for the quantitative description of composite materials.
- Electron Holography
- In-situ experiments like in-situ heating and in-situ cooling e.g. for investigating phase changes
