In situ XRR, GID, and XANES characterization of 2D molybdenum carbide layers on liquid metal catalyst.

The main goal of the proposed experiment is the structural characterization of 2D Mo2C layers during the growth on the liquid metal catalyst, i.e., layer thickness, separation distance from the substrate, in-plane lattice constant, roughness, valence state, and geometrical distortions. Furthermore, during this experiment, we will demonstrate the feasibility of concomitantly applying X-ray diffraction and X-ray absorption spectroscopy to characterize thin layers grown on liquid metals.
