Working on numerical studies of field evaporation phenomena and performing materials characterization is at the core of atom probe tomography and related field-ion microscopy research. The length- and time-scale bridging nature of the mechanisms involved, combined with the fact that atom probe and electron microscopy complement each other, substantiates why research data management solutions for atom probe need to work seamlessly across the condensed-matter physics and the materials engineering communities. Therefore, NFDI-MatWerk and FAIRmat have teamed up in the first funding period and analyzed the consequences for the infrastructure which lead to several working software products for characterizing microstructural features from measured point cloud data. In the next funding period, this team plans to continue their efforts.
Main requirements:
|
| Main Task Area: TA-WLE Other related Task Areas: TA-SAI |
| Possible connections within NFDI: FAIRmat II: Task E.2 Data Federation and Integration, Task D.1 Data Model and Standards and G3 Interconnectivity |
| Material/Data: Experimental characterization and atomistic simulation of material microstructures |
| Main Success Scenario:Through the analysis workflows of the measured or simulated atomistic data, users get more precise information and a deeper understanding of their results, with regard to the formation and interplay of the different elements of the microstructure. |
| Added value for the MatWerk community: Workflows and software tools are designed in coordination with FAIRmat such that the exchange of data, metadata, ontologies, and concepts for data curation between the two NFDI consortia is ensured without loss of information. In this way, both consortia can mutually benefit from ongoing improvements in the infrastructure for condensed-matter physics (FAIRmat) and the interpretation of microstructure data (NFDI-MatWerk). |
Our focus will be on achieving a harmonized description for modelling field evaporation and the reconstructing of material volume, as well as the semantic characterization of microstructural features from measured atom probe data.
Furthermore, it is a necessity to assure that all solutions continue to function with the established proprietary software that is currently used by the majority of the atom probe community.
