High resolution (scanning) transmission electron microscopy investigation of the surface and other defects in CCSS (B03)

• Subject Area: Inorganic Molecular Chemistry - Synthesis and Characterisation ; Mathematics ; Metallurgical, Thermal and Thermomechanical Treatment of Materials
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 506711657

Project B03 will investigate how changes in surface chemistry and structural order (e.g., segregation and ordering versus random solid solution) as well as other defects will affect CCSS properties. The atomic configuration at the surface will be determined with highest spatial resolution using aberration-corrected (S)TEM imaging and analytical techniques. Attention will also be paid to changes caused by annealing and electrochemistry. Possible surface segregation, ordering phenomena and atomic distances within the (sub)surface will be evaluated in cross-section.
