    • The width of the stop band can be estimated either from reflectivity or transmission spectra in the single-crystal approximation without absorption.

    • Each diffraction peak can be homogeneously broadened due to the finite thickness of the domains.

    • The width of the stop band at the oblique incidence (FWHM=40 nm at θ=30°) is larger than at normal incidence (FWHM=18 nm, see Table I).

    • note
    • In fact scattering occurs both in front of and behind the sample. However it is very difficult to detect light scattered in front of the sample since its intensity is dominated by the Bragg diffraction.

    • note
    • For incidence along the normal (θ=0), the directions of the diffuse halo and the additional beam coincide. However, for θ≠0, the diffuse halo remains centered around θ as expected, whereas the additional beam remains centered close to the normal, as observed in Fig. 7.

    • note
    • It is interesting to note that in the spectra of scattering at very large angles (β>40°) the shape of the background changes, exhibiting an increase of the intensity towards shorter wavelengths. This indicates the presence of wavelength-dependent Rayleigh-type scattering on smaller features with broader directionality which becomes visible against the reduced background at large β.
