X-ray Crystal Truncation Rod
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 delta function like Bragg peaks. Presence of crystalline surfaces results in additional structure along so-called truncation rods (linear regions in momentum space normal to the surface). Crystal Truncation Rod (CTR) measurements allow detailed determination of atomic structure at the surface, especially useful in cases of oxidation, epitaxial growth, and adsorption studies on crystalline surfaces.

Famous quotes containing the words crystal and/or rod:
“While that the sun with his beams hot
Scorched the fruits in vale and mountain,
Philon the shepherd, late forgot,
Sitting beside a crystal fountain,”
—Unknown. The Unfaithful Shepherdess (l. 1–4)
“Alas,
For the tireless heart within the little
Lady with rod that made them rise
From their noon apple-dreams, and scuttle
Goose-fashion under the skies!”
—John Crowe Ransom (1888–1974)
