摘要：

An asymmetry in the grazing incidence diffuse x-ray scatter from a 420 Angstrom silver film grown on an offcut (111) silicon substrate has been interpreted as arising from fractal-like step-bunching of terraces at the substrate-layer interface. The variation of diffuse scatter with the component of scattering vector normal to the film surface indicates the presence of different lateral correlation lengths for the two interfaces.
