    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.
