Abstract:
We apply molecular dynamics methods for simulation of in situ processes in new combined TEM/SPM technique. The atomic structure transformations of a gold nanobridge between two contacts are studied in processes of loading-unloading and friction cycles, vertical, lateral, diagonal and zigzag motion. In all cases only a single-atom contact is broken at the final stage of deformations. The deformation process strongly depends on the velocity of fracture and schemes of motion.
