Transmission Electron Microscopy

3MAD2 Transmission Electron Microscopy Materials and Chemistry S9
Lessons : 15 h TD : 0 h TP : 0 h Project : 0 h Total : 15 h
Co-ordinator : Sylvie Malo
Prerequisite
Crystallised solids - Real Crystals - Synthesis and structural methods
Course Objectives
The aim of the course is to make known to students the potential of transmission electron microscopy and related techniques in the field of structural and microstructural characterization of materials. The theoretical aspect of the technique is simplified to the minimum necessary for its rational use and the detailed development of this method of study, based on numerous examples, is presented for its practical use. The examples are chosen to allow a correlation with the materials treated in the other courses dealing with inorganic materials
Syllabus
