| Kurzbeschreibung | Dieser 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). | ||||
| Inhalt | This 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 | ||||
