摘要：
We developed an experimental method for the atomic scale deformation mechanics of nanomaterials based on high-resolution transmission electron microscopy (HRTEM). The dynamics of the sub-nano Newton scale force and conductance can be simultaneously observed at intervals of 260 mus during direct atomic imaging by HRTEM. The strain, stress and strain-stress relation to analyze the mechanical properties of individual nanometer-sized structures are directly measured. Details of the method and typical results of solid point contacts and single atom wires were reviewed.
