abstract = {New possibilities are presented for the characterization of
A$^{III}$B$^V$ mixed superlattice compounds by the
complementary use of synchrotron diffraction topography and
rocking curves. In particular, using a synchrotron white
beam and the section diffraction pattern of a 5 µm slit
taken at a 10 cm film-to-crystal distance, it was possible
to reproduce a set of stripes corresponding to interference
fringes. These are analogous to the interference maxima
revealed in high-resolution rocking curves, but are created
by the changes in orientation of the planes inclined to the
surface which are induced by unrelaxed strain. The section
diffraction topographic method enabled examination of the
sample homogeneity along the narrow intersecting beam. This
was important in the case of the present sample containing a
twin lamella in the InP substrate wafer. Both the section
and projection Bragg case topographic methods enabled the
crystallographic identification of the twin lamella. Another
characteristic feature indicated in the section topography
was the bending of the stripes corresponding to the
superlattice peaks close to the boundaries of the twin
lamella. The most probable interpretation of this phenomenon
is an increase in the thickness of the deposited layers
close to the lamella, together with possible changes in the
chemical composition, leading to a decrease in the mean
lattice parameter in the superlattice.},
