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:
“In a few days I’ll have lived one score and three days in this vale of tears. On I plod—always bored, often drunk, doing no penance for my faults—rather do I become more tolerant of myself from day to day, hardening my crystal heart with blasphemous humor and shunning only toothpicks, pathos, and poverty as being the three unforgivable things in life.”
—F. Scott Fitzgerald (1896–1940)
“Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.”
—Bible: Hebrew Proverbs 22:15.
