The and interplanar spacings in samples with different miscut angles and miscut directions. The errors in miscut angles and interplanar spacings are smaller than the graphical symbols.
The symmetric 004 and asymmetric 444 reciprocal lattice maps measured experimentally for a sample with 1.5° miscut angle along the GaAs direction.
(a) The dependence of FWHM values for longitudinal and transverse scans in different reflections on the coefficients and , and (b) the Williamson-Hall plot. The sample has a 1.5° miscut along . Systematic errors in FWHM values are smaller than graphical symbols.
Densities of uncorrelated 60° misfit dislocations as a function of miscut angle for all investigated samples.
The comparison of the scans for two samples with the miscuts 1° (sample 1) and 1.5° (sample 2) along .
