Short Description
The core facility for electron microscopy is equipped with a Zeiss Ultra Plus Field Emission-Scanning Electron Microscope (FE-SEM), a JEOL JEM-F200 Transmission Electron Microscope (TEM) with a Cold-FEG electron source and the necessary instruments for the sample preparation such as the Precision Ion Polishing System (PIPS II) from Gatan.
The FE-SEM can image inorganic as well as organic sample structures with a high resolution. This microscope is unique due to the large quantity of analysis methods such as backscatter- and secondary electron imaging, energy dispersive X-ray spectroscopy, Electron Back Scattered Diffraction, cathoduluminescence (CL), micro X-ray fluorescence, Electron-Beam-Induced Current-Method and the possibility to perform in-situ electrical characterization of conducting samples in the micrometer range using micromanipulators.
The TEM is equipped with a Cold-FEG electron source (energy dispersion of 0.3 eV). With this TEM it is possible to visualize inorganic as well as organic sample structures down to the sub-nanometer regime (resolution limit TEM: 0.08 nm & STEM: 0.15 nm). The TEM can be operated at accelerating voltages of 60 kV, 80 kV and 200 kV and is therefore also suitable for biological and beam sensitive samples. The microscope stands out due to the high brightness of the electron source, the large acquisition angle of the windowless EDX detector (just below 1 sr), a backscatter and secondary electron detector (BEI) and the possibility to acquire high resolution images with element contrast with the high angle annular dark field (HAADF) detector.
The PIPS II is being used in sample preparation for transmission electron microscopy. The PIPS II from GATAN is able to thin conventional and cross-section samples with Ar-ions with an accelerating voltage ranging from 0.1 kV to 8 kV down to a thickness of 10 nm. A built-in high resolution digital optical microscope allows a site specific sample preparation. The sample can be cooled with liquid nitrogen to reduce heat induced artefacts in the sample during the ion bombardment. Furthermore, focused ion beam samples (FIB) can be thinned to the desired thickness.
