Microstructure design of quasi-single-crystalline and smooth model thin films (A02)

• Subject Area: Synthesis and Properties of Functional Materials
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 506711657

A02 designs the microstructure of noble metal CCSS (beginning with preselected systems, continuing based on results of A01) to enable atomic-scale experiments. The aim is to obtain smooth quasi-single-crystalline films with up to micrometre-sized grains. The crystallographic orientation of these grains is determined, enabling the orientation-dependent investigation of CCSS properties. Furthermore, the defect structure of the quasi-single-crystalline films will be altered, enabling elucidation of the effects of defects on electrocatalytic properties (with all B and C projects). A02 provides the second part of the CRC’s material platform.
