Crystal truncation rod
WebX-ray crystal truncation rod scattering is a powerful method in surface science, based on analysis of surface X-ray diffraction (SXRD) patterns from a crystalline surface.For an infinite crystal, the diffracted pattern is concentrated in Dirac delta function like Bragg peaks.Presence of crystalline surfaces results in additional structure along so-called … WebThe adsorption of formic acid induces an atomic roughening of oxidized magnetite (111) surface which we conclude from the quantitative analysis of the crystal truncation rod data.

Since real surfaces are always somewhat miscut from a low index plane, it is important to study the effect of miscuts on crystal truncation rods. We develop a model that describes the truncation rod scattering from miscut surfaces that have steps and terraces. We …
WebX-ray CTR scattering is a rod-shaped X-ray scattering appearing in the direction perpendicular to a crystalline surface (Fig. 130.1a) (Feidenhans’l in Surf Sci Rep 10:105–188, 1989[1]). Sharp truncation of the electron density of crystalline materials at the surface results in the CTRs.
