HL 11: Focus: Advanced TEM spectroscopy - low energy excitations and chemical composition at high resolution (joint session KFM/HL)

Montag, 1. April 2019, 15:00–18:40, PHY 5.0.20

The recent progress in transmission electron microscope (TEM) based spectroscopies in terms of spatial, temporal and spectral resolution allows to address new regimes of electronic and vibrational excitations and therefore widened our understanding of condensed matter. This session focuses on recent developments and applications of spectroscopy techniques in the TEM, in particular electron energy loss spectroscopy in the low-loss regime for optical properties and core-loss regime for chemical analysis, at both atomic and medium resolution. Moreover, contributions on ultrafast techniques as well as energy dispersive X-ray spectroscopy, hardware and technique developments, theory and simulation and data processing will be discussed.
