KurzbeschreibungDer Einführungskurs in Transmissionselektronenmikroskopie (TEM) bietet neuen Nutzern die Möglichkeit theoretisches Wissen und praktische Kenntnisse in TEM zu erwerben
Lernziel- 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.
InhaltUsing 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.

KurzbeschreibungDieser Fortgeschrittenenkurs für hochauflösende Transmissionselektronenmikroskopie (HRTEM) bietet Vorlesungen, die sich auf HRTEM- und HRSTEM-Bildgebungsprinzipien, die zugehörige Datenanalyse und Simulation, sowie Phasenwiederherstellungsmethoden konzentrieren.
Lernziel- Learning how HRTEM and HRSTEM images are obtained.
- Learning about the aberrations affecting the resolution in TEM and STEM and the different methods to correct them.
- Learning about TEM and STEM images simulation software.
- Performing TEM and STEM image analysis (processing of TEM images and phase restoration after focal series acquisitions).
InhaltThis course provides new skills to students with previous TEM experience. At the end of the course, students will know how to obtain HR(S)TEM images, how to analyse, process and simulate them.

Topics:
1. Introduction to HRTEM and HRSTEM
2. Considerations on (S)TEM instrumentation for high resolution imaging
3. Lectures on aberrations, aberration correction and aberration corrected images
4. HRTEM and HRSTEM simulation
5. Data analysis, phase restoration and lattice-strain analysis
