Crystal truncation rod

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.
