327-2125-00L Microscopy Training SEM I - Introduction to SEM
|Dozierende||S. Rodighiero, A. G. Bittermann, L. Grafulha Morales, K. Kunze, J. Reuteler|
|Periodizität||jedes Semester wiederkehrende Veranstaltung|
|Kommentar||Number of participants limited to 9.|
Master students will have priority over PhD students. PhD students may still enrol, but will be asked for a fee (http://www.scopem.ethz.ch/education/MTP.html).
|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.
