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. WebJan 4, 2024 · Here we use a combination of X-ray crystal truncation rod analysis and ab initio molecular dynamics to probe the pre-nucleation liquid layering at the sapphire–aluminium solid/liquid interface ...

X-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 … See more A particle incident on a crystalline surface with momentum $${\displaystyle K_{0}}$$ will undergo scattering through a momentum change of $${\displaystyle \mathbf {Q} }$$. If $${\displaystyle x}$$ and $${\displaystyle y}$$ represent … See more Surface features in a material produce variations in the CTR intensity, which can be measured and used to evaluate what surface structures … See more To obtain high-quality data in X-ray CTR measurements, it is desirable that the detected intensity be on the order of at least $${\displaystyle 10^{9}{\tfrac {photons}{mm^{2}s}}}$$ . To achieve this level of output, the X-ray source must typically be a See more For a given incidence angle of X-rays onto a surface, only the intersections of the crystal truncation rods with the Ewald sphere can … See more WebX-ray crystal truncation rod scattering is a powerful method in surface science, based on analysis of surface X-ray diffraction patterns from a crystalline surface. For an infinite … WebFeb 1, 1998 · We have investigated the unreconstructed (0001) surface structure of sapphire (α-Al2O3) by grazing incidence X-ray scattering. Modulations along the crystal truncation rods were analyzed in order to determine the chemical nature of the terminating plane, and the structural relaxations of the first few atomic planes below the surfoce.
