5. Energy barriers ΔW for different mechanisms of dislocation nucleation in a model Au–Pd nanowire with a radius of 5, 10, and 50 nm (according to [61]). The diagrams of these mechanisms are shown below the histogram (from left to right): sliding of a partial mismatch dislocation (PD) from the surface of the nanowire along the interface inside the shell, sliding of a complete mismatch dislocation (PD) from the surface of the nanowire along the interface inside the shell, sliding of the PD from the surface of the nanowire along the interface inside the core, sliding of the PD from the surface of the nanowire along the interface inside the core, crawling of the PD from the surface of the nanowire to at the interface, the emission of sliding black holes by the edge of the core of the dipole, the emission of a sliding PDN by the edge of the core of the dipole. Here R is the radius of the nanowire, 2l is the side of the square section of the core. |
