| Outline of Final Research Achievements |
Using grazing-incidence small-angle scattering (GISAXS) with computed tomography (CT), we have reconstructed the spatial distribution of a thin gold (Au) layer buried under a thin poly(styrene-b-2-vinylpyridine) (PS-b-P2VP) layer. Owing to the difference between total reflection angles of Au and PS-b-P2VP, the scattering profiles for Au nanoparticles and self-assembled nanostructures of PS-b-P2VP could be independently obtained by changing the X-ray angle of incidence. Reconstruction of scattering profiles allows to separately characterize spatial distributions in Au and PS-b-P2VP nanostructures.
