Abstract

In order to investigate lattice distortions in CdTe crystal when smaller ZnTe4 tetrahedra are added as impurities, we measured Zn Kα X-ray fluorescence holography (XFH) on Cd0.96Zn0.04Te mixed crystal, and obtained atomic images around the Zn atoms in a wide spatial range. The image intensity of the first-neighbor anion Te atoms is remarkably weak compared to those of the distant atoms. Thus, the lattice of this mixed crystal is distorted only in the first nearest neighbor range. This result is different from those of diluted magnetic semiconductors Zn1-xMn xTe and Cd1-xMnxTe, or In1-xGa xSb mixed crystal, whose lattice distortions continue to the intermediate range up to the five chemical bonds.
