Propagation and Interaction of Edge Dislocation (Kink) in the Square Lattice
Abstract
The propagation of kink or edge dislocations in the underdamped generalized two-dimensional Frenkel-Kontorova model with harmonic interaction is studied with numerical simulations. The obtained results show that exactly one line of atoms can be inserted into the lattice, which remains at standstill. However, if more than one line of atoms are inserted into the lattice, then they will split into several lines with alpha = 1, where alpha presents the atoms inserted. In other words, only the kink with alpha = 1 is stable, while the other kinks are unstable, and will split into alpha = 1 kinks, which remain at standstill.
