扫描透射电子显微镜层析成像和原子探针层析成像都是纳米尺度上的三维技术。我们在这里展示了通过分析相同体积的铝银合金试样的技术的组合。这种比较使我们能够通过实验直接可视化每种技术的理论上已知的伪影，从而深入了解用于重建的最佳参数并评估每次重建的质量。在纳米级的三维精确形态和成分信息的技术相结合，提供了一个新的水平的材料表征和理解的路线。由爱思唯尔公司出版
Scanning transmission electron microscope tomography and atom-probe tomography are both three-dimensional techniques on the nanoscale. We demonstrate here the combination of the techniques by analyzing the very same volume of an Al-Ag alloy specimen. This comparison allows us to directly visualize the theoretically known artifacts of each technique experimentally, providing insight into the optimal parameters to use for reconstructions and assessing the quality of each reconstruction. The combination of the techniques for accurate morphology and compositional information in three dimensions at the nanoscale provides a route for a new level of materials characterization and understanding.
