FAIRifying ARPES: a Route to Open Data & Data Analytics — •Ralph Ernstorfer1,2, Tommaso Pincelli1,2, Patrick R. Xian2, Abeer Arora2, Florian Dobener3, Sandor Brockhauser3, and Laurenz Rettig2 — 1TU Berlin, Germany — 2Fritz-Haber-Institut Berlin, Germany — 3HU Berlin, Germany
While angle-resolved photoemission spectroscopy (ARPES) is the most direct probe of crystals' electronic structure, the globally collected ARPES data have not been merged into an open experimental electronic structure database in equivalence to well-established atomic structure databases. We discuss a data format based on NeXus [1] as a concept for unifying the data structure for all types of photoemission experiments including time-, spin-, and time-resolved ARPES [2]. The aim is to immediately enable preprocessed data and metadata shareability according to FAIR data principles, employing existing public storage and archiving research data infrastructures such as Zenodo, OpenAIRE, and Nomad/FAIRmat. Ultimately, the multidimensional photoemission spectroscopy (MPES) format is designed to allow high-performance automated access, providing experimental databases for high-throughput material search [3].
