Research Abstract

High-speed time-resolved measurement systems of (1) grazing-incidence small-angle and wide-angle X-ray scattering (GISWAXS) to evaluate domain/molecular-scale surface /thin-film structure, (2) microbeam X-ray diffraction and scattering to evaluate local structure / layer structure in the thickness direction, and (3) anomalous small-angle X-ray scattering (TRASAXS) to evaluate meso-scale stucture utilizing the X-ray absorption edge of specific heavy elements were successfully established using synchrotron radiation at undulator-type SAXS BLs in SPring-8 for organic polymer thin films under external stimulation.
