| Kurzbeschreibung | Der Einführungskurs in Rasterelektronenmikroskopie (SEM) betont praktisches Lernen. Die Studierenden haben die Möglichkeit an zwei Elektronenmikroskopen ihre eigenen Proben oder Standard-Testproben zu untersuchen, sowie von ScopeM-Wissenschafler vorbereitete Übungen zu lösen. |
| Lernziel | - Set-up, align and operate a SEM successfully and safely. - Accomplish imaging tasks successfully and optimize microscope performances. - Master the operation of a low-vacuum and field-emission SEM and EDX instrument. - Perform sample preparation with corresponding techniques and equipment for imaging and analysis - Acquire techniques in obtaining secondary electron and backscatter electron micrographs - Perform EDX qualitative and semi-quantitative analysis |
| Inhalt | During the course, students learn through lectures, demonstrations, and hands-on sessions how to setup and operate SEM instruments, including low-vacuum and low-voltage applications. This course gives basic skills for students new to SEM. At the end of the course, students with no prior experience are able to align a SEM, to obtain secondary electron (SE) and backscatter electron (BSE) micrographs and to perform energy dispersive X-ray spectroscopy (EDX) qualitative and semi-quantitative analysis. The procedures to better utilize SEM to solve practical problems and to optimize SEM analysis for a wide range of materials will be emphasized. - Discussion of students' sample/interest - Introduction and discussion on Electron Microscopy and instrumentation - Lectures on electron sources, electron lenses and probe formation - Lectures on beam/specimen interaction, image formation, image contrast and imaging modes. - Lectures on sample preparation techniques for EM - Brief description and demonstration of the SEM microscope - Practice on beam/specimen interaction, image formation, image contrast (and image processing) - Student participation on sample preparation techniques - Scanning Electron Microscopy lab exercises: setup and operate the instrument under various imaging modalities - Lecture and demonstrations on X-ray micro-analysis (theory and detection), qualitative and semi-quantitative EDX and point analysis, linescans and spectral mapping - Practice on real-world samples and report results |
