Abstract
The stress field of a dipole of disclinations located in the central part of a cylindrical nanowire has been first calculated within the linear elasticity theory. The gliding of two edge dislocations of the same Burgers vector has been then investigated from a Peach–Koehler force analysis. More specifically, the unstable and stable equilibrium positions have been determined in the nanowire. A stability diagram for the dislocations has been finally displayed vs. the length and strength of the disclination dipole.
