The development of aberration-corrected electron microscopy, which allows individual atom imaging with unprecedented precision, was recognised by the 2011 Wolf Prize in Physics. However, only a very limited amount of the wealth of information obtainable from such microscopes is currently exploited. By collecting a maximal data set of electrons scattered in manifold different ways and using the fundamental theory of electron-specimen interaction, this project will realise the huge potential of this untapped data. This will improve the utility of scanning transmission electron microscopy far beyond its current level. Applying these new techniques will expand our understanding of the structure and function of advanced materials.

像差校正电子显微镜的发展，使单个原子成像具有前所未有的精度，获得了2011年沃尔夫物理学奖的认可。然而，只有非常有限的数量的丰富的信息，可从这样的显微镜目前被利用。通过收集以多种不同方式散射的电子的最大数据集，并使用电子-样品相互作用的基本理论，该项目将实现这一未开发数据的巨大潜力。这将提高扫描透射电子显微镜的实用性远远超过其目前的水平。应用这些新技术将扩大我们对先进材料的结构和功能的理解。
