The characterization of the AlAs\GaAs multilayers based on the modelling of
the X-ray scattering is discussed. The structural parameters regarding the
thickness of the bilayer components and the vertical and lateral variation
s (interface roughness) were assessed from low and high angle scan modes. T
he diffuse scattering analysis showed that both lateral and vertical correl
ation of the interface roughness develops in this LPOMVPE grown system. (C)
