    Sammanfattning : The interaction of energetic ions with matter is highly relevant for a wide range of applications. Amongst them, material characterization employing ion beams is widely used due to its capability of high-resolution composition depth profiling. LÄS MER

  7. 20. Morphology studies of thin films of polyfluorene: fullerene blends

    Författare :Cecilia Björström; Kjell Magnusson; Mats Fahlman; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik;

    Sammanfattning : The formation of thin films of polymer blends by spin-coating from solution is characterised by rapid solvent quenching, a process that results in non-equilibrium morphologies. Thin films of conjugated polymer blends are used as the active material in polymer solar cells, in which the morphology may have drastic effects on device performance. LÄS MER
