Grazing Incidence SAXS
|
|
For thin porous films, regular SAXS measurements need to be adjusted so that the scattering signal comes from the thin film only. Hence, the x-ray beam should not reach into the supporting material structure, but should only graze the surface of the film. This is enabled by GISAXS and thus, allows for routine assessment of quality and regularity of solid-supported nanostructures, assessment of structural phase-transitions at changing temperature, pressure or hydration, and assessment of the preservation of nanostructures’ orientational order with respect to the solid surface it is attached to after phase transitions. |
