After a PhD on method development in scanning transmission electron microscopy (centered on strain and mesoscopic E-field measurement techniques) at the CEA Grenoble (France) from 2013-2017, Benedikt Haas became a postdoc for three years in the group of Prof. Christoph T. Koch at the Department of Physics & IRIS Adlershof of Humboldt-Universität zu Berlin. Since 2020, he is a permanent scientist there and responsible for the Nion HERMES ultra-high energy resolution scanning transmission electron microscope which he utilizes to develop novel electron microscopy techniques that he applies to relevant materials science questions. His focus is scanning transmission electron microscopy in the form of ‘4D-STEM’ and (momentum-resolved) high-resolution EELS. Materials he is or has been working on comprise 2D materials, hybrid inorganic/organic systems, topological insulators, nanowires and nanoparticles, different semiconductor hetero-structures and many other systems. He is working on the registration and live processing of 4D-STEM data (GBs/s) and FAIR (findable, accessible, interoperable and re-usable) data structures.
