Olena Fedchenko works as a PostDoc in the group of Prof. Elmers (KOMET335) within the DFG CRC/TRR288 Elasto-Q-Mat, project B04 "Momentum microscopy of highly correlated systems under strain". Her research focuses on the development and implementation of a novel type of photoemission detector system, namely a time-of-flight momentum microscope. With this new tool at head, she aims to study the electronic and geometrical structure of complex materials with exotic electronic properties, such as TMDCs, Kagome systems, Eu-based 122 compounds, altermagnets, etc.
The preliminary work leading to the successful application for the DFG grant was carried out within the framework of Dr. Fedchenko’s TopDyn Early Career Researcher Excellence Support project. The topic of this project was "Novel contrast mechanisms in transmission momentum microscopy for the investigation of structure and dynamics of topological materials". Supported by TopDyn, she used this valuable time to gain the necessary knowledge, experience and first experimental results. At the same time, fruitful collaborations were established, which were crucial for her successful application for the DFG research grant.
Dr. Fedchenko recently received a two-year DFG grant for the project "Investigation of the structure and ultrafast dynamics of topological materials with inversion symmetry breaking using transmission momentum microscopy".
