Two recent works on emerging memory materials exposed to heavy ion radiation were published in ACS Nano and Journal of Applied Physics. These publications have been prepared in close cooperation with CEA LETI and CNRS LTM (Grenoble, France) and Fraunhofer IPMS CNT (Dresden) in the framework of the European Projects WAKeMeUP and StorAIge funded by EU and National Authorities, as well as in close collaboration with the Advanced Electron Microscopy Group of TU Darmstadt and the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt. The experiments reveal that irradiation-induced effects in hafnium oxide- and GeSbTe-based memory materials strongly depend on the initial crystallinity and composition of the active layers. Our experimental approach combining nonlocal and local characterization with electrical investigations provides important groundwork for investigations of irradiated digital but also analog memristive devices in future.
