Abstract
The formation of a prismatic dislocation loop in the two interfaces of a three-layer nanowire has been theoretical studied from a static energy variation calculation, when the three layers are submitted to misfit strains. Depending on the misfits and different radii of the layers, the possibility of formation of the dislocation loop at the different layer interfaces has been characterized and a stability diagram is provided for the structure. The effect of the external radius of the nanowire is also investigated.
