Research Abstract

Atomic processes of mechanical processing were performed and directly observed in situ by time-resolved high-resolution transmission electron microscopy at spatial resolution of 0.1nm and time resolution of 1/60 s.
Nanometer-sized tips of gold and silicon approached, and were contacted, bonded, deformed and fractured inside a 200 kV electron microscope using a piezo-driving. Contact boundaries of a few atomic columns width in gold, silicon/silicon-oxide/silicon tunnel junctions, and quantum dots of silicon/gold-cluster/silicon were produced. A few layers near the surfaces and contact-boundaries were responsible for the bonding and separation processes. Atomic scale contact or non-contact type surface-scanning similar to that in scanning probe microscopy was performed by the same method. The mechanical removal of one atomic layer was also demonstrated. New kinds of atomic scale mechanical tests, such as friction test, compressing, tensile and shear deformation tests were proposed.
