WebMay 8, 2024 · Crystal truncation rods are used to study surface and interface structure. 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 … 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 slow down the mouse cursor
