MS 4: Functional thin films

This session focusses on functional thin films and advanced structured materials targeted for applications in a wide range of energy and information technologies, including intriguing physical effects at interfaces of epitaxial complex oxide systems, electron and ion conductors, photovoltaics, thermo-electrics, dielectrics, and resistive switching. The optimization of these devices, from materials’ design to applications, requires a thorough knowledge of the structural, physical, and chemical properties, its interactions with the environment and the role of interfacial effects, for which recent technical innovations in electron microscopy hardware and software have provided a fertile ground for their analysis with unprecedented spatial and spectral resolution. We welcome contributions to latest developments at the forefront of scientific achievements and impact in the design, synthesis, characterization, and applications of functional thin films.

MS 5: Functional organic materials

The revival of polymers, organic molecular/carbon-rich materials and composites thereof is not only due to the development of high-efficiency (semi)conductors and their enhanced environmental stability. Basic reactants appear unlimited prospectively yielding sustainable products at globally needed amounts. Those materials already contribute to the global energy revolution and facilitate a vast variety of applications such as energy conversion/storage, (flexible) printed electronics, catalysis, rapid prototyping, lightweight construction as well as drug delivery. The serious issue of microplastics in the environment needs to be addressed, e.g., by means of biodegradable material design.
This session will cover novel micro- and nanocharacterization techniques (like 4D-STEM, UHR-EELS, cryo-EM, X-ray micro-spectroscopy, fluorescence OM) and modern sample preparation (like plasma-FIB cross-sectioning, (cryo-)ultramicrotomy, plunge freezing) to investigate individual materials (molecules, thin films, particles, fibers), composites and complex devices for understanding structure formation, function, and degradation. It includes modern in situ methodology stressing strategies to minimize electron-beam induced alterations.
