Project Details
Description
An Imaging Filter (Gatan) was attached to a 200 kV transmission electron microscope. This instrumentation enables the recording of parallel EEL-spectra from small specimen regions and of elemental maps at nanometer resolution. The project centred on the development of new methods, such as 1. improvement of specimen preparation by a new low-angle ion milling apparatus, 2. computer programs for image processing (correlation of elemental maps), 3. quantification of elemental maps (concentration maps).
The Imaging Filter was successfully applied to a broad range of materials science problems, such as characterization of precipitates and grain boundaries in steels and alloys, analysis of heterogeneous ceramics, semiconductor devices, composite materials and polymers.
