Abstract

We used multiple energy x-ray holography (MEXH) to image the local atomic environment of Zn atoms doped in a GaAs wafer using synchrotron radiation and a multielement solid-state detector. The obtained atomic images revealed that the Zn atoms occupied substitutional site. By the comparison of the reconstructed images 1.41 Å above and below the emitter atom, the suppression of twin images due to MEXH was confirmed experimentally for certain atoms.
