Local structural characterization of gold nanowires using extended X-ray absorption fine structure spectroscopy

Gold nanowires were prepared via seed-mediated growth process. Standard X-ray powder diffraction pattern of nanowires and foil are nearly identical. This is in accordance with electron diffraction analysis of mature nanowires, the wires grow along the [1 1 0] directions. XAS indicates that CN of gold nanowires was slightly smaller than that gold foil.
