| Research Abstract |
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.
