Role of Structure and Morphology in Organic Electronics
In the past decade, polymers and small molecule thin films have found use in organic electronics as organic FETs (OFETS), photovoltaics (OPV) and LEDs (OLEDS). The way the organic molecules pack and the nanoscale morphology of these films (which is often different than in bulk) have a strong impact on the film functionality. To determine this structure and relate this to the film functionality, we have used grazing-incidence X-ray diffraction (GIXD) and small X-ray angle scattering (SAXS).
