X-ray super-cell crystallography of self-organized Co/Au(111) deposits

Abstract : We report in situ Grazing Incidence Small Angle X-ray Scattering (GISAXS), performed on self-organized Co/Au (111)deposits during growth. The surface reciprocal space associated with the dots periodicity (similar to10 nm) is investigated. The quantitative combination of GISAXS and STM yields non-destructive information about buried layers. For Co/Au(111), a periodic interfacial microstructure persists even after the film free-surface smoothing is observed.
