Research Abstract

We developed an x-ray optics including one or two Si (004) channel-cut crystals, a feedback-control system for stabilizing an arc-sec angular divergence, refractive micrometer lenses, and limiting slits. A vertical angular divergence of 1.3 arc sec and a horizontal beam size of about 2 um were evaluated for 12.4 keV incident x-ray photons.
We investigated a gold single crystal surface in H2SO4 solution and a thin film and nanowires epitaxially grown on a sapphire single crystal. Rocking curves of diffraction intensities and emission profiles were observed. The curves look like dynamical x-ray diffraction ones for an almost perfect crystal. Dynamical x-ray diffraction phenomena took place in the gold and sapphire substrate, which was quite surprising and unexpected.
Our research outcomes indicate that one will apply the standing wave technique to a structural analysis for a surface system and buried interface of thin film on a non perfect crystal like a metal and oxide material.
