    Phase change thin films for non-volatile memory applications
    (Cambridge : Royal Society of Chemistry, 2019) Lotnyk, A.; Behrens, M.; Rauschenbach, B.
    The rapid development of Internet of Things devices requires real time processing of a huge amount of digital data, creating a new demand for computing technology. Phase change memory technology based on chalcogenide phase change materials meets many requirements of the emerging memory applications since it is fast, scalable and non-volatile. In addition, phase change memory offers multilevel data storage and can be applied both in neuro-inspired and all-photonic in-memory computing. Furthermore, phase change alloys represent an outstanding class of functional materials having a tremendous variety of industrially relevant characteristics and exceptional material properties. Many efforts have been devoted to understanding these properties with the particular aim to design universal memory. This paper reviews materials science aspects of chalcogenide-based phase change thin films relevant for non-volatile memory applications. Particular emphasis is put on local structure, control of disorder and its impact on material properties, order-disorder transitions and interfacial transformations. © 2019 The Royal Society of Chemistry.

    Solvent influence on the surface morphology of P3HT thin films revealed by photoemission electron microscopy
    (Cambridge : Royal Society of Chemistry, 2019) Niefind, Falk; Karande, Shubhangi; Frost, Frank; Abel, Bernd; Kahnt, Axel
    Only rigorous understanding of the relationship between the nanoscale morphology of organic thin films and the performance of the devices built from them will ultimately lead to design rules that can guide a structured development on the field of organic electronics. Despite great effort, unraveling the nanoscale structure of the films is still a challenge in itself. Here we demonstrate that photoemission electron microscopy can provide valuable insights into the chain orientation, domains size and grain boundary characteristics of P3HT films spun cast from different solvents at room as well as at elevated temperatures. © 2019 The Royal Society of Chemistry.
