Pm. Len et al., ATOMIC IMAGING BY X-RAY-FLUORESCENCE HOLOGRAPHY AND ELECTRON-EMISSIONHOLOGRAPHY - A COMPARATIVE THEORETICAL-STUDY, Physical review. B, Condensed matter, 50(15), 1994, pp. 11275-11278
We consider from a theoretical viewpoint the direct imaging of atoms a
t and near the surfaces of solids by both x-ray-fluorescence holograph
y (XFH) and electron-emission holography (EEH). The more ideal nature
of re-ray scattering makes XFH images superior to those in single-ener
gy EEH. The overlap of real and twin features for pairs of atoms at ra
can cause their XFH or EEH atomic images to cancel for certain combin
ations of wave vector and \a\ The relative merits of XFH and EEH for s
tructure Studies are considered.
