Atomic scale solid state direct bonding in time-resolved high-resolution transmission electron microscopy was realized by using the piezodriven specimen holder. The structural variations of atomic arrangements in approach, contact, bonding and separation processes between two gold tips were observed at atomic scale. It was found that the nanometer-sized gold tips contact spontaneously when the tips approach at the critical distance corresponding to a few atomic distance underi intense electron irradiation. The crystallographic boundary forms after the contact. A few layrs near the surfaces and bonding-boundaries are responsible for the bonding and separation processes. New kinds of atomic scale mechanical tests such as the friction test, the compressing, tensile and shear deformation tests were proposed.

通过使用压电驱动样品架实现了时间分辨高分辨率透射电子显微镜中的原子级固态直接键合。在原子尺度上观察了两个金尖端之间的接近、接触、键合和分离过程中原子排列的结构变化。研究发现，在强电子辐照下，当纳米级金尖端接近相当于几个原子距离的临界距离时，纳米级金尖端会自发接触。接触后形成晶体边界。靠近表面和粘合边界的几层负责粘合和分离过程。提出了摩擦试验、压缩、拉伸和剪切变形试验等新型原子尺度力学试验。
