KurzbeschreibungThe course focuses on the fundamental understanding and hands-on knowledge of analytical Transmission Electron Microscopy (ATEM) techniques: electron dispersive X-ray analysis (EDX), energy filtered TEM and electron energy loss spectroscopy (EELS). The lectures will be followed by demonstrations and acquisition sessions TEM instruments.The lectures on statistical treatment of raw data sets and on
