Figure 3.17. (a) Specular X-ray intensity of a DIP film with 20.6 nm thickness.
Bragg reflections up to the seventh order are seen. (b) Magnification of the specular
scan from the region of total external reflection across the first specular DIP Bragg
reflection. The inset displays a rocking scan across the DIP(001) reflection which
exhibits FWHM as small as 0
