Resonant scattering of polarized soft x-rays (P-SoXS)

The collaboration with the group of Prof. Harald Ade (North Carolina State University, Raleigh, USA) lead to an important publication in the latest online version of Nature Materials. Resonant scattering of polarized soft x-rays was used to demonstrate the possibility to detect orientational order in organic systems relevant for molecular electronics on length scales below the present limitations of x-ray microscopy. P-SoXS also reveals scattering anisotropy in amorphous domains of all-polymer organic solar cells where interfacial interactions pattern orientational alignment in the matrix phase, which probably plays an important role in the photophysics. The energy and q-dependence of the scattering anisotropy allows the identification of the composition and the degree of orientational order in the domains.
