Abstract

The novel technique of X-Ray Fluorescence Holography (XFH) is used to investigate the structure of the Fe-based high temperature superconductor parent FeTe around Fe as the emitter atom. Holograms of an FeTe single crystal are recorded at several energies above the Fe K edge. The data are analyzed using the scattering pattern extraction algorithm SPEA-L1. The reconstruction of the atomic images on the Fe plane yields unit cell parameters different from those obtained by X-ray diffraction (XRD) measurements. The Te height is slightly higher than the XRD data, suggesting an effect of the excess Fe atoms in the crystal.
