我们使用多能X射线全息术（MEXH）图像的局部原子环境的Zn原子掺杂在GaAs晶片使用同步辐射和多元素固态探测器。得到的原子图像显示，Zn原子占据替代位。通过对发射极原子上下1.41埃处的再现像的比较，实验证实了MEXH对某些原子的孪晶像的抑制。
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 Angstrom above and below the emitter atom, the suppression of twin images due to MEXH was confirmed experimentally for certain atoms.
