T. Gog et al., MULTIPLE-ENERGY X-RAY HOLOGRAPHY WITH ATOMIC-RESOLUTION, Journal of electron spectroscopy and related phenomena, 92(1-3), 1998, pp. 123-129
Recent approaches to achieving atomic resolution with holographic meth
ods and directly image atomic structures in the bulk at surfaces and i
nterfaces of solids have become increasingly successful. Multiple-ener
gy X-ray holography (MEXH), a particular implementation of such a meth
od, is reviewed and its first applications to bulk crystals and nano-c
lusters suspended in a crystalline matrix is presented. MEXH utilizes
X-rays to generate an interference field within the sample, then deter
mines its strength at specific atomic sites from fluorescence emission
s. Scanning reciprocal space, a hologram is recorded from which local
atomic structures can be reconstructed by Fourier transformation. Imag
e aberrations known to distort single-energy holograms are effectively
suppressed in this novel multi-energy technique. (C) 1998 Elsevier Sc
