| 227-0390-00L | Elements of Microscopy | 4 credits | 3G | M. Stampanoni, G. Csúcs, A. Sologubenko | |
| Abstract | The lecture reviews the basics of microscopy by discussing wave propagation, diffraction phenomena and aberrations. It gives the basics of light microscopy, introducing fluorescence, wide-field, confocal and multiphoton imaging. It further covers 3D electron microscopy and 3D X-ray tomographic micro and nanoimaging. | ||||
| Learning objective | Solid introduction to the basics of microscopy, either with visible light, electrons or X-rays. | ||||
| Content | It would be impossible to imagine any scientific activities without the help of microscopy. Nowadays, scientists can count on very powerful instruments that allow investigating sample down to the atomic level. The lecture includes a general introduction to the principles of microscopy, from wave physics to image formation. It provides the physical and engineering basics to understand visible light, electron and X-ray microscopy. During selected exercises in the lab, several sophisticated instrument will be explained and their capabilities demonstrated. | ||||

| Abstract | The introductory course on Transmission Electron Microscopy (TEM) provides theoretical and hands-on learning for new operators, utilizing lectures, demonstrations, and hands-on sessions. | ||||
| Learning objective | - Overview of TEM theory, instrumentation, operation and applications. - Alignment and operation of a TEM, as well as acquisition and interpretation of images, diffraction patterns, accomplishing basic tasks successfully. - Knowledge of electron imaging modes (including Scanning Transmission Electron Microscopy), magnification calibration, and image acquisition using CCD cameras. - To set up the TEM to acquire diffraction patterns, perform camera length calibration, as well as measure and interpret diffraction patterns. - Overview of techniques for specimen preparation. | ||||
| Content | Using two Transmission Electron Microscopes the students learn how to align a TEM, select parameters for acquisition of images in bright field (BF) and dark field (DF), perform scanning transmission electron microscopy (STEM) imaging, phase contrast imaging, and acquire electron diffraction patterns. The participants will also learn basic and advanced use of digital cameras and digital imaging methods. - 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 TEM microscope. - Practice on beam/specimen interaction, image formation, Image contrast (and image processing). - Demonstration of Transmission Electron Microscopes and imaging modes (Phase contrast, BF, DF, STEM). - Student participation on sample preparation techniques. - Transmission Electron Microscopy lab exercises: setup and operate the instrument under various imaging modalities. - TEM alignment, calibration, correction to improve image contrast and quality. - Electron diffraction. - Practice on real-world samples and report results. | ||||

| Prerequisites / Notice | No mandatory prerequisites. Please consider the prior attendance to EM Basic lectures (551- 1618-00V; 227-0390-00L; 327-0703-00L) as suggested prerequisite. | ||||
| 327-2129-00L | Analytical Electron Microscopy: EDS | 1 credit | 2P | P. Zeng, L. Grafulha Morales, K. Kunze, A. Sologubenko | |
| Abstract | The main goal of this hands-on course is to provide students with fundamental understanding of underlying physical processes, experimental set-up solutions and hands-on practical experience of analytical electron microscopy (AEM) technique for microstructure characterisation, specifically Energy Dispersive X-ray Spectroscopy (EDS) and spectrum imaging (SI) technique. | ||||
| Learning objective | - understanding of physical processes that enable the EDS technique and data evaluation algorithms; - hand-on experience of data acquisition and evaluation routines including o practical understanding of different data acquisition set-ups, o optimization of acquisition parameters for most reliable quantification of the results, o the knowledge of the available and most reliable quantification algorithms and their handling o the knowledge of data evaluation routines and possible handicaps for reliable elemental content distribution analyses and material composition quantification o the effect of the specimen geometry on the data and experimental solutions for minimization of the artefacts | ||||
| Content | This advanced course provides analytical EM techniques to the students with prior EM experience (TEM or SEM). At the end of the course, students will understand the physical processes that enable the EDS technique and data evaluation algorithms and apply the technique for their own research. - Introduction to analytical electron microscopy: theory and instrumentation. - Lectures on EDS, WDS - Practical on EDS-SEM: data acquisition and analysis. - Practical on EDS-TEM: data acquisition and analysis. The hand-on trainings are to be carried-out on a real-life specimen, provided by lecturers and / by students. | ||||
