Abstrakt

Grazing-Incidence Small Angle X-ray Scattering (GISAXS) and X-Ray Photon

Correlation Spectroscopy (XPCS) studies of island growth in two different systems are presented:

5 ML of iron on MgO(001) and 10 ML of iron on Au(001). Due to a missing conducting surface

Fe/MgO thinner than approximately 20 ML could not be studied previously by common methods

like STM. Fe/Au(001) is interesting as atoms of gold diffuse easily through iron layers and form

precipitates. The coarsening dynamics of these precipitates is investigated by XPCS in GISAXS

geometry. Their growth depends on the crystallographic directions of the substrate and correlates

with the morphology measured by STM microscopy. Measurements were performed at the ESRF in

Grenoble.
