Abstract

This introductory course on Scanning Electron Microscopy (SEM) emphasizes hands-on learning. Using ScopeM SEMs, students have the opportunity to study their own samples (or samples provided) and solve practical problems by applying knowledge acquired during the lectures. At the end of the course, students will be able to apply SEM for their (future) research projects.

Objective

- Set-up, align and operate a SEM successfully and safely. - Understand important operational parameters of SEM and optimize microscope performance. - Explain different signals in SEM and obtain secondary electron (SE) and backscatter electron (BSE) images. - Operate the SEM in low-vacuum mode. - Make use of EDX for semi-quantitative elemental analysis. - Prepare samples with different techniques and equipment for imaging and analysis by SEM.

Content

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 are able to align an SEM, to obtain secondary electron (SE) and backscatter electron (BSE) images and to perform energy dispersive X-ray spectroscopy (EDX) semi-quantitative analysis. Emphasis is put on procedures to optimize SEM parameters in order to best solve practical problems and deal with a wide range of materials. Lectures: - Introduction on Electron Microscopy and instrumentation - electron sources, electron lenses and probe formation - beam/specimen interaction, image formation, image contrast and imaging modes. - sample preparation techniques for EM - X-ray micro-analysis (theory and detection), qualitative and semi-quantitative EDX and point analysis, linescan and spectral mapping Practicals: - Brief description and demonstration of the SEM microscope - Practice on 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 - Practice on real-world samples and report results
