Description
High-throughput methods are increasingly employed to accelerate the discovery and investigation of new materials. In our group we produce combinatorial thin-film libraries with varying compositions in both X and Y direction. This drastically reduces the time spend on synthesis when mapping a compositional space and at the same time increases the need for detailed characterization and data management.
This talk will focus on how NOMAD is used in our research and helps us conduct our daily research in the lab. Firstly, we track our samples all the way from cutting the substrates to the right size to annealing after deposition. NOMAD is also used to keep track of the usage and state of the instrument and targets used during the processes to better understand long term changes and contaminations. Lastly, we use NOMAD to organize and analyze our characterization data and to combine results from different mapping measurements done on one combinatorial sample. The new characterization techniques introduced to NOMAD are covering methods to determine compositional (EXD, XPS), structural (XRD) and optical properties (PL, ellipsometry).
