Abstract
We have applied small angle scattering in grazing incidence beam geometry on a time-of-flight neutron instrument. Due to the broad wavelength distribution provided for a specific incident beam angle the penetration depth of the neutron beam is varied over a broad range in a single measurement. The near surface structure of polymer micelles close to silicon substrates with distinct surface energy is resolved. It is observed that the very near-surface structure strongly depends on the surface coating whereas further away from the surface bulk like ordering is found. A more pronounced ordering is found close to surfaces with high surface energy.
