Layer and interface formation of defect-tolerant functional materials as revealed by X-ray spectroscopy (S05)

• Subject Area: Solid State and Surface Chemistry, Material Synthesis ; Physical Chemistry of Solids and Surfaces, Material Characterisation
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 538767711

Project S5 (Bär) focuses on a family of X-ray spectroscopies to yield near-surface specific information on the evolution of a material’s chemical and electronic properties as the solid grows and interacts with its surroundings (with C3). Electronic structures and energy level alignments will be determined together with C5, S1, S2, S4, M1, M2. Furthermore, the setup of ALD infrastructure will allow for film formation to be investigated step by step by fully exploiting the advantage of in-system prepared samples and automated sample transfer and measurement routines. Details of gas phase and solution chemistry will be explored by in situ studies using synchrotron light routinely, together with S3, M3.
