表面和界面反应的结构、键合和化学动力学，以及因此大多数材料性质都与每个原子所处的能量景观内在地联系在一起。在这里，我们证明了在电子束激发下运动的原子可以用来探测沿（受限）台阶边缘的能量景观，提供有关原子尺度势的信息。实验探索原子势的技术有望利用电子束预测原子间的制造。
Structure, bonding, and chemical dynamics of reactions at surfaces and interfaces, and therefore most material properties are intrinsically tied to the energetic landscape in which each atom resides. Here, we demonstrate that a moving atom under electron beam excitation can be used to probe the energy landscape along (confined) step edges, providing information about atomic-scale potentials. The techniques for experimentally exploring atomic potentials holds promise for predictive atom-by-atom fabrication using electron beams.
