Why is it important?
A peculiar kind of intensive X-ray standing wave is analytically shown to exist. Such an X-ray interference field is localized in the vicinity of a surface of a crystalline superlattice and its amplitude decays exponentially in both directions perpendicular to the surface. The appearance of the standing wave is accompanied by a deep dip in a chosen Bragg peak of the superlattice.
Perspectives
In the present communication, we suggest a specific X-ray standing wave that is concentrated in the vicinity of a surface of a crystalline superlattice. Under the two-beam Bragg-case X-ray dynamical diffraction by a nearly perfect crystal, a normalized maximum intensity of the standing field is equal to 4 and decays exponentially deep into the crystal. In contrast to these features, the concentrated wave is characterized by a reso- nantly enhanced intensity which dies out exponentially both in and outside of the superlattice.
