Valence Sensitive X-ray Fluorescence Holography of Magnetite

摘要

X-ray fluorescence holography(XFH)is an atomic resolution, element sensitive experiment that can directly provide a 3-dimensional picture of the atoms surroundinga selected element in a material1. Fluorescent X-rays from the target element (reference wave) is scattered by the surrounding atoms (object wave), and their interference is recorded as holograms. A 3D atomic image can be directly reconstructed from the holograms by numerical processing.
