Real-space determination of local atomic arrangements of CCSS (B05)

• Subject Area: Experimental Condensed Matter Physics ; Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 506711657

The sub-project B05 uses scanning tunneling microscopy for an atomic-scale view of the surfaces of CCSS in real space, their elemental composition and distribution of the elements across the surface. Because of the low chemical sensitivity of scanning tunneling microscopy, the challenge to discriminate five different elements on a surface demands the development of novel tools to determine the SSA of CCSS in real-space. Three main approaches, i.e., dz/dV mapping, chemically sensitive imaging, and local phonon spectroscopy, will be supplemented by discrimination via spectator molecules, CO or water. The results will aid the fabrication of targeted CCSS and their modelling in the partner projects.
