Abstract
The paper is devoted to a two dimensional x-ray diffraction study of non ideal (GaAs(1 - c)Pc)/(GaAs) superlattice showing the broadening of satellite reflections which lie on a line making a small constant angle with the [00L] reciprocal lattice rod containing the nodal reflection. This additional broadening is due to nonzero lateral gradient of the phosphorus concentration -- dc/dy -- which implies dividing crystal volume into coherent scattering domains (CSDs). A model of coherently diffracting domains with rectangular composition modulation waves that have a different amplitude and wavelength in each domain is presented.
